why are your father/mother- in law allowed access in the access room ??? Its the time for you and your child to spend time with each other. If child is very small than the mother is allowed to be there with the child, but not your wife's parents. You should strongly protest /bring this to notice of Counsellor / Court by means of an application to allow your space with your child.
Also your wife will have a considerable influence on the child as she gets to spend most of the time with your child n theres nothing you can do about it.
Only when she influences your child against you /does it openly in the access room you can point out the same to the supervisor / counsellor to intervene.
Pls learn to ACCEPT you cant expect more from your child at this stage.....n most importantly your child is innocent and should not be blamed for turning out biased , against you !!!
