Bad Parenting

I don't know if just teaching him foul languange would get him taken away. You would have to prove her to be an unfit parent and it tends to be harder to do with mothers. However I do think they would have a problem with her drinking around him and having so many men around. The men would probably be the worst part. I definitely think she is making some very bad parenting decisions. Have you guys tried talking to her to see what is going on? I definitely wouldn't want my children in that kind of situation. I would try talking to her and telling her it is affecting him in a very negative way. If she cares about him she will want to do what is best for him. He is going to pick up so much from her because at this early stage they soak up everything that is going on around them even when you think they aren't paying attention. I would try what you could with her because it would be awful to have to take him away from her but if there is just no reasoning with her then you have to do what you have to do. Proof is always necessary in court cases because unless you can prove that she is unfit then they will leave him with her. I hope this has been atleast somewhat helpful and that you guys find a good solution for all who are involved. Good luck hun! :)
