Hello everyone! I have a question: my 2-month-old baby only turns over on one side. I'm worried about possible plagiocephaly. Could I buy an orthopedic pillow? Or would massage be helpful? I do massage at home but the baby cries, I think I might be hurting him or doing it wrong... I went to a neurologist, but I forgot to tell her that he always looks on one side. She said everything is normal and Dr. Karatan prescribed something. I forgot to mention that we had a cyst in our head, I was worried about it. Ultrasound showed no cyst, yay! I forgot all about it.
