Grandmother with sole custody
I have sole custody of me grandson and have had it since he was 6 months he is now 5 years old. His mother has never had any interest in him during this time as she moved from nys to Florida married a man who never met the child then had a child with him she shows up occasionally (very rarely) has since moved to Germany (husband in the army) is pregnant with her 3rd child and now wants to leave her husband in Germany bring her other 2 children to nys and try to get the child I have custody of. Help I have no idea where to go with this for advice as she never had an interest in the child prior and her contact with him is almost non existent
