plagio/brachycephaly caused by crib mattress that are too firm?

[Guest guest]

I had this thought last night, just want to bring it up here and see if anyone

has the similar feeling. The crib mattress that we use is a safety 1st foam

mattress we bought from Walmart. When I was preparing baby's stuff before my

son's birth, I was told to get firmest mattress out there. so that's what we

did. but just now I realize that this mattress is much firmer than the one I

sleeps on! and when I press it with my fist, I can only create a little

deformation in there. I'm suspecting that would have contributed to my son's

plagio since too much pressure was on his skull when he sleeps.

So moms of plagio babies please tell me, how firm are your crib mattresses?
