Helmet?

I want to say they usually give it until about 6months to see if skull shape is able to correct itself. I would definitely keep advocating for him though if you’re still concerned when he goes for 6month check up

My first had torticollis (stiff neck on one side from position inuteru, fwiw I gave birth vaginally, that doesn't necessarily make a difference here) and that caused plagiocephaly. We did see an infant PT to help with the stiff neck once and got some exercises to do to loosen and strengthen his other side. The pictures you posted make it kind of hard to see exactly what is going on, the pictures they will take are from straight above and then draw a line ear to ear and nose to middle of back of head and want the four quadrants equalish and then straight from the side for ear placement related to the curve of the head and front of the face straight on for symmetry of eyes and ears, but it looks really minor from the pictures you posted. I say that not to say don't ask for a referral if you feel it necessary, always advocate for your child if you feel it is the right thing to do! But I do want to say that it looks really minor and there is good reason they wait until 6 months because the plates in the head don't fuse until a year so there is plenty of time still and once they are sitting and crawling these things really do fix themselves if they were minor up until that point. My sons was worse than your pictures, although not terrible either, and it completely corrected itself by doing tummy time and encouraging him to look both ways when he slept and diaper changes and then once he was upright more often it all adjusted itself before his plates fused around a year.
