DD 5 and DS3. Grandfather keeps picking up DD by picking her up between the legs and patting her bottom. In short hands are all over private places during play. Makes DH's blood boil. I didn't think anything of it as I thought it the norm, but realise family has a history of not respecting boundaries/privacy issues while I was growing up, so I actually have no idea what is acceptable. Appreciate that it becomes less appropriate as the child gets older, but where to draw the line? (There is absolutely no sugggestion of sexual abuse I have to stress). Please help me guage what you see as appropriate. It is tearing me apart.
