I am a FTM and my 5 week old sons head has gotten flat on the right side. When we went to the doctor for his 2 week check up the doctor noticed he always wants to put his head on the right side. The doctor told me to try to make him put it on the left side to avoid flat head and his neck being stiff. So I kept moving his head to the left and he’d just keep moving it back and I didn’t really know what to do. About 2 weeks ago I noticed his head does look different on the right side and I was telling my husband I didn’t know what to do bc he always just turns back to the right side. My husband suggested we put something there so he can’t turn to the right. This has been working but now idk what to do about the right side being kind of flat

Does anyone know how to fix his right side or if I even can? I’m so worried he’s going to have a messed up head
