My baby has a flat head help!!!!

Brandy

So my baby boy is not 3 months and two weeks and has been developing a flat head.

I have tried the positioning and the less laying down thing. Please please give me as many suggestions as you can.

I would like the helmet to be a last resort. We live in china so all beds are harder than in the West.

I am scared that his poor little head will stay this way forever.
