Any other reason for dipped fontanelle

[Lulubum]

My DS, 3 and a half months old, appears to have a constantly dipped fontanelle and was wondering if any other mums have had this with their babies. I really noticed it about a month ago and I know dehydration is one of the main reasons for the dip but even after a feed its still the same, and pulsing too. I spoke to the HV today who said it's probably nothing but the speak my the GP just for my own peace of mind. I'm not the type of person to question professionals so when I see the GP and they tell me everything is absolutely fine because he's happy, feeding well, loads of wet nappies (and pooing at least 5 times a day (is that normal))and putting on weight like a champ I'll accept it but still feel worried and not know what to say to them. He has also recently started sleeping through the night so will have his last feed at around 9pm then wake up around 7am and when I feel his head in the night it isn't dipped. Which has me completely confused because wouldn't going for long periods mean more of a dip??? Please help with what to say to GP or if I'm being a bit silly and it's actually quite normal for some babies.

Not a terribly useful reply, but a anted to reassure. Pulsing is completely normal - both my children's fontanelles used to do this, it is weird to see but its just their pulse. Always freaked me out a bit.
With regards to the dip as you've said he's feeding well and loads of wet/dirty nappies then it can't be dehydration. I'd go and see GP and have them check how dipped it is and get some reassurance - to my hand it always feels a little dipped. I suppose because there is no bone there and I'm very gentrly pressing to feel it. Buy do actually ask them directly are there any other reasons for dipped fontanelle - I honestly don't know, but think if all else is good its probably fine.

Thank you for the reply. It's always better for me to hear it from a mum who has been through something similar to know it's normal.

O didn't have any problems with my daughters fontanelle, also lucky she's had dark full head of hair from the beginning, but I have a friend who's daughter's fontanelle was dipped and GP said she was fine, and also a few years back I used to look after a friend's baby and her fontanelle was always pulsing and the hair on it was also raised, it was do scary and creepy but she was also fine and she's all normal now. I would see a GP but don't stress about it until then

I've panicked myself over the fontanelle too! Then I found this and felt much better... fontanelle

It says when a baby's known to be sick then a sunken fontanelle can be a sign of dehydration. But then the baby would also have sunken eyes, a dry mouth, and decreased or absent tears.

Otherwise it says "if the baby is healthy and not dehydrated, the fontanelle will indeed sink into the head a bit when the baby is upright since blood is not filling the central vein underneath it as fully. No big deal. If it bothers you, just lay the baby back in the horizontal position - voila - the fontanelle is full again."

Hope this helps!

My two baldy babies had/have this-literally a dip in the head! Ds1's didn't go completely until 2! (It was 4.5fingers at birth so you can imagine on a new born!) He noticed his DB's pulsing yesterday, it can freak you out. Wet tongue and wet nappies, don't worry at all

Thank you all. That's so reassuring. I think having the HV say to get it checked made me panic. My DD had a head full of thick black hair so I probably just didn't notice with her when she was a baby. DS has lovely ginger hair so more noticeable.
