my son is 1 month old. his current weight is 3.6 kg. birth weight was 3.05kg. yesterday I have noticed his right side of head is flat , ear of that side is touching shoulder and size of ear is big as compared to other one.. his side preference is right side... right side fore head is outside..although he can rotate his head to left side.. some time with support and some time on his own. I think he has congenital torticollis. what to do. ?? will it affect his mental health...what to do...?? do I go for physio therapy
