Are these episodes taking place at your house or hers? If she is at your home, then I think you can just step in if you here her reprimanding him and say "I've got this, thanks" then take his hand and lead him away. If you are out at a public place or somewhere common like grandma's than I would do the same thing. If you are at her home, then I think she has a right to expect the kids to follow any rules she wants at her home. I personally think she also has the right to enforce those rules at her home by telling your child no if you aren't making him follow the rules. If you disagree with some of her "house" rules than I wouldn't take your child over there unless absolutely necessary. I only say this because it drives me up the wall when someone lets their kid come to my house and jump all over my furniture or something similar and then stands there and says nothing while they do that. I think I am well within my rights in my own home to say "Johny we don't jump on the couch at my house" However, I would expect my daughter to follow the rules at someone else's home. If I feel someone has some rules that are little much for my liking I would pick a common place to meet and then discipline just my child. If she is being really over the top with the discipline and your son truly isn't acting out of order, I do think you should say in as nice of a way possible (in private with just you and her around), "I would really appreciate if you would leave Johny's discipline to me, his mom" You don't need to give an excuse or examples, but just repeat this as many times as necessary until she gets the point. I would expect her to probably have her feathers ruffled though, so plan on it, and don't let it bother you. As you said, your his mom and his needs come before her feelings.
