DS1 had a helmet for a moderate flat spot on the right side of his head. This has made me a little anxious.

DS2 is almost 2 months. He sleeps in a RNP but can easily turn his head in both directions. He isn't a huge fan of tummy time but will do it a few times a day for five minutes. I've noticed the very back of his head is getting a flat spot.

I guess I'm looking for reassurance that it will work itself out and it pretty normal at this age.
