hi ladies,
I was wondering if anyone could point me in a direction about information on babies head flat spots.. my DS is 12 weeks and one side on the back of his head is beginning to be slightly flatter than the any other part of his head.. I have tried moving his head to the other side when hes asleep but he just rolls it back, I do a little bit of tummy time, could probably do a lot more but he doesn't really like it, he is generally a really happy baby so when I put him on his tummy and he doesn't like it I don't do it for long coz I don't like seeing him upset (no mother does, I know)

but if anyone could give me some pointers on what I should be doing, that would be awesome!!
tia
