My son who's 10, has recently been letting his standards slip when going to the toilet. I won't go in to too much detail but he hasn't been checking that he's left the toilet as he found it after use. The first few times I told him he needed to go back to the toilet to check what he's done. Today however, I felt it was time to have a more serious talk and explain that he absolutely needs to check the toilet after use because leaving it like that is unacceptable. Later on this evening he did it again. I don't think it's out of wanting to, based on what he's done I think he's just being very careless. However, my mother who's staying with us at the moment, saw what he did and told him off as I was also telling him off. When I told him what his punishment was, my mother jumped in and said "I don't even think that's enough. She then told him he needs counselling. Twice.
I didn't say anything in front of my son but I told my mother in a room away from my son that what she said was not okay. I explained that it was hurtful and wrong. Was I wrong?
