Do you think my babies head is flat from the back?

I feel like his head is flat from back especially a little on top I have told his pediatrician that I was concern about his head shape he did say he agree it was a little flat. He recommended me to go a hospital for children where they will decide if he did or not. After his first haircut I can’t stop starring at his head I just feel like he does need a helmet even though they don’t told his head was flat but it wasn’t as flat to the point where he needed one. So he didn’t get one. I really wish he did though just to correct it. I feel like that’s how they head shape is going to stay now. I have seen a few men head and you can tell it’s an odd shape and I just feel like that’s how my son head will be also should I insists get a helmet maybe ask my doctor again since you can see more after his haircut?

Heres a better idea
