Parents often worry about lumps and bumps on a baby’s head unnecessarily. Babies normally have ridges and soft spots on their head for a while after birth. Many have a type of swollen gland that parents can feel when rubbing the head. All of this is normal.
Skull anatomy
Let’s begin with a brief overview of a baby’s head. We are born with many bones in our skull. This allows the head to be squeezed out of the birth canal as the bony plates move together or even overlap one another.
Sometimes you don’t really notice much with these bones, but other times they overlap one another noticeably after birth. When a baby has a lot of head distortion due to overlapping of skull bones, we call it molding. It can make the head look pointed – which is often called cone head. It can also make the head look flat on one side.
The good news? Even really odd looking heads are usually normal. Molding tends to resolve without intervention over the first few days of life.
Soft spots
There are 1-2 “soft spots” at birth. Usually the one on top to the head (the anterior fontanelle) remains open enough to feel for the first 18-24 months of life. The one towards the back of the head (the posterior fontanelle) is unable to be felt by about 2 months of age. It is often so small at birth that it’s not recognized.
Many parents fear that touching a soft spot will somehow damage the baby’s brain. Normal touching won’t hurt, even from a 2 year old sibling. There are several layers of skin and other tissues protecting the brain.
Doctors will feel the soft spots during routine check ups to be sure they are the right size for the growth of the baby’s head. There’s a lot of variation here, so if you question the size of your baby’s soft spot, discuss it at a visit with the doctor. He or she will need to not only feel the soft spot, but also will look at overall head growth, baby’s development, and the shape of the head.
Bruises and bleeding
Coming out of the birth canal can be traumatic for both mother and baby (and often for fathers too). Sometimes babies have a big soft or squishy bump on one side of the head, which usually is essentially a large bruise.
Bruises can cause yellow jaundice.
Any bruise can increase the risk of yellow jaundice in a newborn, so your doctor might watch your baby more carefully for this over the time that the blood is resorbed. This is because yellow jaundice is caused by breakdown of blood cells. Most babies show yellow color in their eyes and face. Even if it progresses to their chest and abdomen it can usually self-resolve with proper hydration, but it should be monitored. If the level gets too high it can be managed. Talk to your doctor if you’re concerned.
Cephalohematoma vs caput saccedaneum.
The two most common types of bruising are cephalohematoma and caput saccedaneum.
A cephalohematoma develops when there is bleeding between the skull and the bone lining called periosteum. Since it is outside the skull, it doesn’t affect the baby’s brain. It covers only one of the bones, and never crosses one of the suture lines.
Caput succedaneum is swelling of the scalp in a newborn. It develops from bleeding one layer above the periosteum in the skin. It can cross the bone areas since it’s not limited by the lining of the bone (periosteum). You will notice a soft, puffy swelling on the baby’s scalp, usually in the area that first came out during birth. Some will show bruising.
Both of these conditions can lead to increased risk of yellow jaundice due to breakdown of the blood collections, but usually self resolve without complications. If baby seems uncomfortable due to this area, discuss with your hospital nurse or doctor.
The picture below attempts to show the layers of bleeding described here and includes more uncommon (and more concerning) types of bleeding. Babies who have deeper bleeds need proper medical management. For information about subgaleal hematoma, see Seattle Children‘s website. Epidural hematomas are very rare in newborns.
Flat spots
Flat spots are common, especially if babies prefer to always look to one side. This can cause the forehead to seem to bulge on one side or an ear to appear closer to the face than the other ear. This is usually due to baby laying one direction most of the time, allowing the brain to grow all directions but spot baby is laying on.
Babies always need to sleep on their back until they start to roll on their own, but this can encourage a flat head. It’s important to get baby to lay looking right sometimes, left other times. Supervised tummy time is helpful too. I recommend starting tummy time on day one. The earlier you start tummy time the less they seem to hate it!
When you hold and feed baby, alternate arms because they will look toward you and by simply holding in the right arm sometimes, left arm other times, they will turn their head. If your baby resists turning his head, check out this Torticollis information.
Lymph nodes
One of the most common head worries that brings parents to the office is a pea-sized (or bigger) movable bump on the back of baby’s (or even an older child’s) head. This is usually an occipital lymph node.
When I say it’s just a lymph node, some parents automatically worry about lymphoma.
Don’t go there.
Most of us remember having a swollen lymph node (AKA swollen gland) under our jaw or in our neck when we are sick. When they develop on the back of the head, it is usually from something irritating the scalp, like a scalp probe during labor, cradle cap, or bug bites in older kids. They can remain large for quite a while (often seeming to come and go when kids have scalp irritations), but unless they hurt to touch, enlarge rapidly, are red and hot, or a child looks sick otherwise, I don’t worry about them.
TL:DR
In short, most lumps and bumps on your baby’s head are normal. If you’re worried, bring your baby in to have your pediatrician look and feel.

My son had what looks like a bump in the middle of his forehead, to touch you can’t feel anything but you can see clearly it with certain expressions he makes. It’s almost like a mark underneath his skin, can you shed any light on this he is now 5 months and doesn’t seem to have got better or worse.
That sounds like something to ask at his next well visit so you can get reassurance or if the doctor is concerned it can be further evaluated.
My son has had a bump on the back of his head for a while (he’s now 6 months). It doesn’t move…it’s almost like it’s his skull sticking out. His ped is not worried about it but I got an xray just in case and it came back normal. Its changed. Now he has this protrusion on both sides of the back of his head and therefore now has a strangely shaped head! Pediatrician is still not concerned but I want to see a specialist to ease my mind. Who do I see? A neuro? Neurosurgeon?
I just found a few bumps on the back of my baby’s head… I did refuse the Vitamin K shot…. He has an appointment on Tuesday, so I will be asking.. 🙁
If you did not do Vitamin K, risks of bleeding increase. If there are any other symptoms, you NEED to go to the ER. Babies die or have permanent disabilities without vitamin K. You don’t mention how old your baby is, but if he’s under 6 months, I’d watch him very carefully. I have a post dedicated to Vitamin K, if you’re open to reading it. https://questforhealthkc.com/2017/12/30/7-vitamin-k-myths-busted/
Omg it’s so dangerous to refuse the vitamin k shot.. I would take him in right away. That’s not fair to him at all if your refusal causes him issues
My daughter is now 5. She’s has had a hard bony like knot on the top of her head closer toward the middle. I noticed it when she was 2 that she had the lump. She has never complained about it, but I was just curious as to what I could possibly be. Any ideas?
Without seeing and feeling it, it’s hard to say. Since it’s been there so long you should bring it up at her next visit with her pediatrician.
thanks a lot. I had notices small movable lumps on number8. both sides. showed doctor said normal..Again today I noticed a small (less then a pea) movable lump on number 4 of left side.No any symptoms. However your article helped
I’m glad it helped. Of course if you’re concerned, talk to your doctor.
I noticed 5 moveable lumps on the back of my baby’s head. Do I need to worry about it ?
If you’re still worried after reading the above information, talk to your child’s doctor.
Thank you for addressing this! I’ve noticed a small lump on both sides of the back ofmy sons head and was about to call his pediatrician for an appointment before his next 2 mo well baby, but I’m reassured now and will wait until his regular appointment to speak with her.
I’m glad this helped! If things change, call your doctor, but if all else is well just bring it up at your appointment.
We saw a lump on my daughter front head when she was two weeks old n now she is 2 months plus is there any thing to b worried about ?the left side is a litle bit swollen than the right side of her from score or head
I can’t say if any specific lump is normaml or not. Talk to her doctor about it at your next visit and schedule specifically for it if you’re worried, especially if she has other symptoms with it.
Same here! Born 3/22 and pea bumps on both sides. Feel so much better now!
I’m glad to hear that this helped. It’s a very common issue!
I noticed my baby swells in the middle of the two eye blow (should I call it nasal bridge) am not sure how they call it but whenever she cries it swells as if there’s much meat there and it happened from birth,she’s now 3 years old but still happens is that normal????
That is a question that is best answered by her doctor. Since it’s been there all her life, it is fine to wait until her next appointment unless it is getting worse. Make a note to bring it up at her next well child check!
My child has been to the e.r, she has been seen by her pediatrician and has another appointment this friday. Its been about a month or so since i first noticed it, she has a solid disfigured lump on the back of her head that isnt moveable, as if it is a part of her skull. It appears that it has gotten much bigger since i first noticed it. She has another lump too, but this one you can kinda move around where as the other one you cant. I feel like 6 months is too long to wait to find out if she has something other then a swollen lymph node. I dont know what im asking exactly, i just want peace of mind and for these bumps to go away.
It sounds like at least two physicians have already seen this and you’re doing a good job of being your child’s advocate. If you’re worried, you should bring it up again. If you get reassurance from multiple physicians, it is more likely something that you can continue to monitor. Without seeing your baby, I can’t offer any specific advice, but I’m glad you’re advocating for your baby!
Hi
My baby have a big bumb on his back head. He is 4months old. I would like to send you some pictures
My email. m771306@gmail.com
I cannot give specific advice. Pictures don’t tell the whole story. Please schedule a visit with your baby’s doctor if you’re worried.
My son has like a thin long dent on the side of his head and it worrys me what can it be ? He has his soft spotvat the top of his head this is something diffrent.
I can’t give specific advice unless I can see a child. Please talk to your son’s physician.
Hi I just discovered the lumps at around #8 as well. Was worried until I read this. But the lumps are on only on the right side and it’s 3. Is that normal? He doesn’t react when I press on them though, he’s 7months.
If there aren’t other concerns, just show your doc the next time you’re in the office. If you’re worried, call your doctor’s office to discuss your concerns and see if you should have them checked out.
What was it ? I just found that on my babies head. So scared…
Same here. Also right side, movable, not tender to the touch and baby turning 7 months
Hi, thanks for this very useful blogs especially for us moms. I just gave birth last 26th Dec, and I found a very soft noticeable spot on the right part of my baby’s head, seems like it has water in it. I am very worried and scared, and tried to search online for some explanation and getting ready myself for our visit on Doctor tomorrow, I hope everything will be fine. In Gods name, amen.
Any time you’re worried, you should talk to your doctor about things. I’m glad you’re going to the doctor today!
How many move able lumps are okay at the base of the skull on both sides? My son is 7 months. He’s sick with a fever.
We all can get what my mom called “swollen glands” when we’re sick. The number doesn’t matter as much as all the symptoms. If he has a lot of pain or rapid swelling of the area, he should be seen. Any of the illness symptoms that concern you should be assessed, such as difficulty breathing or not drinking enough. You can always contact your doctor if you’re concerned. If you don’t have a doctor, call a nurse advice line.
Thank you for this. I just found a small bump around #8 on my 14 month old daughter. It seems just to appear suddenly. She recently had a bad cold and still has. I can’t be sure if runny nose is the cold or a “symptom” of some sort. It moves around and it doesn’t seem to bother her warn I push on it. How long until these bumps go away on there own?
Lymph nodes can remain for months, sometimes people will feel them for years. I always suggest showing them to your child’s doctor at her next routine visit and sooner if there are other concerns, such as fever, pain, increasing size, or just that parent’s intuition and worry!
Thank you. I will make an appointment.
Hi!! My 3 month old just had a CT scan to rule out craniosynostosis and my pediatrician said it came back clear. But she has a ridge on her Sagittal suture and protruding forehead. How easy is it to see a Sagittal suture on a CT scan? And are ridges common still at 3 months?
Elizabeth: You should talk to your pediatrician if you have questions about the imaging.
Hi! My 1yr old son has a ridge from his head down to his forehead. I noticed it since he was 4mos old i think. At first his pediatrician order to do CT but i was terrified and cried infront of him and he came back in a few mins and change his mind he said that lets monitor until 6mos and so after that he just required him to have a helmet beacuse of his flat spot and never do CT because his head size is normal. But until now he still has the ridge i cant help but worry everyday because i think its getting noticeable evrytime i look at him.. any advice? Thank you
It sounds like you should talk to your pediatrician again. He can reassess it to decide if it needs further evaluation or if it’s normal for your son.
I would recommend you take your child to a chiropractor who adjusts babies. My son has a ridge in that area also and since I’ve been taking him to the chiropractor for 2 months now it’s going down. He is 3 months now.
I suspect it would be resolving in this same time frame without chiropractic manipulation. That’s a waste of money. It’s like saying a child is bigger at 3 months than he was at 2 months because you’ve taken him to a chiropractor. No. He’s bigger because he’s getting older and that’s what happens.
My son has staggial cranio CT is best option to diagnose cranio you can have ridges with sutures open hope this helps
How did you make out? My 10 day old has a ridge in the same spot the pediatrician is watching it closely and will do x Ray’s if needed
Thank you! I have made an appointment with our GP in 2 days, but reading this and knowing bubs has no showing symptoms has made me comfortable in my decision not to rush her to the ED.
I’m glad you were able to wait until you could see your regular GP. I hope all is well!
This helped so much. My 1 and a half month old daughter has 2 lumps around #8 on both sides, right and left. But after reading, I feel safe enough to wait until her next routinely check up to ask her pediatrician!
I’m glad you have some comfort after reading this.
How did it go ?
My 10 month old daughter has a lump on the #8. Should I take her to the ER? It seems to bug her when I touch it & it kinda moves & she has a runny nose as well.
I can’t offer advice to anyone specifically unless I’m seeing them. If you’re worried, call her physician. I hope she feels better soon!
oh my gosh my infant has 2 lumps on the occipital areeea. i am worried so much despite that we are financially unable to go see his doctor
I hope that reading the above can ease your fears. Most of the time these bumps are not a concern, but if your baby has other symptoms, he should be evaluated.
Thank you for this article. It was very informative and definitely eased our worries!
Glad to hear that it could be reassuring to you!
Hi my 6 & a half month baby has a bump in the back of the neck close to the
occipital my question is what can it be
If the above images and description don’t answer your question, you should ask your pediatrician. Since I cannot see your baby, I cannot offer specific advice.
Very informative. I’m worried about a bone or gland close to the occipital area.
If you’re worried, bring it up the next time you’re at the doctor’s office. If your baby has other concerning sympotoms or you are worrying a lot, schedule a visit soon to discuss it.
This is so helpful! I’m always worried about every little bump or lump on my 3 month old!
I think that’s why the first time I posted it, it quickly went to my #1 spot. You’re not alone in worrying!
