It seems the subject of flat heads has come up a lot lately so I thought I would share pics of DS1's before and after pics.
As I have mentioned in other posts he wore a DOC Band. There are different types of helmets.
He wore his for about 6 weeks (give or take a couple days).
He got hes when he was 5 months old.
He was not phased by the helmet at all.
This one you can see the changes to the back of his head (flat), the sides right in front of his ears (bulging out), and his forehead (pinched/narrow).
In this one you can see the back of his head (flat - easier to see in you compare the back of his head with his neck) and the top of his head was forming a bit of a high point near the back.
