my baby age is 4.5 months and is rolling over and lifting head. problem is when we hold her then she is looking at down

A. Actually I must tell you this thing you may not know this that there is a partial stability which is 50% usually by completing the time of six months in roll over it is easy but when you hold your child neck does not have total stability which is why its down and that will be seen totally by the time of six months complete so please have patience
