Anyone else get threatened with the helmet? We just went to LO two month checkup Tuesday and his head was in the 98 percentile at 16.4 in. He sleeps so great at night but that has caused a flat spot on the right back side of his whittle head

He hates tummy time but doc says he has to do it more and he has to sleep on the left side. If it isn't better by his 4 month check he will prescribe him a helmet.
Does anyone have experience with this?
Re: Postural Plagiocephaly?
In any case, when I look at her head I don't see any reason for her to have a helmet. I think that the particular pediatrician in the practice we go to is a flake anyway.
