rhiannon had a flat head for a bit till she could get up. it looked worse than it was on her because she has a giganto head. it kind of corrected itself, but i know that in some cases it affects the neck. i would recomend just asking your friend if baby sleeps on one side all the time. dont use that big word, it freaked me out when i heard it for the first time LOL! just let your friend know that it has become more common since all the hype about sids in the early nineties and can be corrected. ::)'s from becca!

My twins had plagiocephaly. I discovered it when they were 9 weeks old. Thankfully, with the repositioning technique, they didn't need to be banded (helmet).

One thing about flat head, it's easier to see from the top, on the mirror! Maybe perhaps you can somehow wander in front of the mirror with her baby and then tell her that you notice that her baby's head isn't as round.
