Hey justmyself,
Welcome to JWD!!
I'm sorry you have to deal with this. Was your son's father a JW before you got pregnant? or did he become one after?
As someone else stated, it's really hard to take a child from his/her mother, just make sure all your ducks are in a row, if he pays childsupport keep all receipts, keep a calander of when he has the child and maybe you should only allow him to take him to meetings when he has visitation, your time with him is yours and should not be taken away for any reason unless you both agree.
check out the website that Junction guy suggested, another memeber of JWD recently went through a custody hearing I think his name is blizfan (?), check the directory maybe he can give you some pointers!!
Good luck
