Call all moms, help with flat head?

Question

So my baby is almost 2months old he was born with a very rounded out head on the left side but flat on the right. It's still a descent shape but feels almost like he could have two different shaped 💀. Regardless of this i bought him a pillow that is geared toward fixing flat head but obviously for the back of his cranium. That being said is it possible to use the pillow to correct the side if i should place his head in there as such. Or is there another way to correct it if at all possible. My major concern however is he is a side sleeper will always prefer that side even in car seat or swing guaranteed to find his head leaning toward the right. I don't know if that will make it worse but I'm really hopeful it won't. I do try to lay him on the other side as much as possible but i don't know if that is such a good thing because i feel if that were to even it out basically means that side had to be pushed in 💁.  Just asking as im at a loss i feel like both sides are correct shapes for a skull just not for only one human if that makes sense. What would you do? What would you recommend?

Answer

I would have him checked for torticollis if he favors one side over the other.  My son had it and we had to do therapy to strengthen his neck muscles. He ended up in a cranial helmet to help round out his head because with the torticollis it wasn’t going to round out on its own. 
If that’s not the case, work on more tummy time. The specialist say that majority of kids with flat heads round out when they start sitting up more throughout the day.
