I posted resently  how BM was working hard at turning SS11 against us by purposely letting him do things we don't and praising him when he's defiant towards us. We tried to ignore it like many said. We also tried to do more fun family things as someone suggested but unfortunately BM only works part time and has way more free time to devote to kissing  SS butt. The most reset development came when we took SS to his yearly physical. BM dislikes his pediatrician because he won't side with her on certain issues so she does not go. SS knows BM does not like his pediatrician and when the pediatrician was telling SS normal things SS was getting very rude for no reason and ended up calling him a bastard. SS later told us when he told BM she laughed and said the pediatrician probably deserved it. We are sticking to our house rules and consequences but they are having less effect now because SS knows when he goes back to BM's house she will purposely make up for whatever we did not let SS do. Here is my question do you think the court would get involved if we brought it to them? The pediatrician knows how BM feels about him and even said BM was probably behind that outburst in his office. SS is careful to defend BM and not say to much but has said BM tells him he does not have to listen to us and that our house rules are dumb. If SS came clean with everything that BM has been doing could BM lose her joint custody?
