Have name changed for this. My DC brought a photo album with some photos exH had printed and given them. One was a photo of my 2 DC in a bath with exH’s younger DD (with current wife). No bubbles, it was clearly a candid shot BUT my DD’s chest and DS’s privates were clearly visible. I messaged him immediately to say this was inappropriate and he claimed it was taken 2 years ago (which means DC were 8 and 9 and his DD was 2/3). We coparent fine most of the time but he occasionally does stuff which I really do not agree with. I feel so powerless, I have already explained to the kids why they are too old to be sharing a bath with anyone and why exH shouldn’t have taken the photo and to tell me if it happens again. I don’t want them to put up with inappropriate behaviour but I don’t want to overreact either (DS was embarrassed and not at all happy about the picture). How do I deal with this kind of crap?
