Dent in back of head

[Ivysmum2020]

Hi, I have brought this up with my HV and waiting for a referral just to get it checked, they don't seem too worried but just Seeing if any other mums have this with their little ones.
I have recently posted about a little flat spot forming on my LOs head
She is 4 months old , and where her flat spot is We have a little dent too.. like her where her soft spot at the back was/is?!
Anyone else's little one ever had a little dent in that place?!
She is thriving other than This, great weight gaining and hitting milestones
I've attached a Picture!

Hiya, so glad I've found this post! My son has a little indent at the back of his head too! Slightly different to this but definitely noticeable enough at 4 months that its concerning. He had it at birth and I am concerned as to what it could be. Will upload a pic tomorrow and maybe see if gp will see us about it x
