I'm not saying I think this is "wrong" but sometimes I do feel like maybe there is an age where this should stop? My husband has a 9 year old daughter from a previous marriage and they still bath together, she has developed without going into too much detail. I do feel slightly uncomfortable with it because I don't see it ending anytime soon and I worry she will be 14 still bathing with him. When I started to go through physical changes I wouldn't even be naked infront of my mum, I worry she's abit too open and I worry maybe she doesn't see the importance of privacy? Her mother has a new boyfriend and I worry she is this open around him too
