My 9 month old son neck leans to one side when in sitting position frequently when he is from 4 months old we have been doing physiotherapy sessions since when he is 7 months old .He is a pre term baby born at 32 weeks and3 days ,his corrected age now is 7 months and 20 days We have done multiple eye check ups and also ROP test and no issues have been found. Would like to understand if this is nuero related and how we can overcome this problem at the earliest thank you
