Dd goes to 3 extra curricular activities. I love her going to these activities, it is my time to heap attention on her and she loves the activities she does. Recently a mum I have known on and off started at swimming, and her child was in dd's group. The child really didn't like it and disrupted the class every lesson, as the dc needed more attention than the rest of the class, her mum had to stay poolside or the child would freak, so I would be left looking after the very difficult 18 m/o as the baby wasn't allowed poolside or in the viewing gallery. Therefore I couldn't watch dd, and missed her achieving her first two badges (pfb I know). Her child is horrid to dd-scratching, biting, kicking, saying really nasty things as dd isn't in to "cool things" (they are 4 btw). Yes, it was dd's fav after school thing, but I figured we had two more that were just me and dd, so we can cope. Now they have started dancing too! And the child is just as disruptive, and still makes a bee-line for dd, and still makes dd's activities a misery, but I don't want to take dd out of them as she enjoyed them pre-scary child. I can't be straight with the mum really as we work together (she is much more senior than me) and we get along really well, and the children used to be play friends until her child became a bit hard to cope with. The dc also turns everything around so tells her mum my dd did the biting, scratching, hitting, and my dd then gets confronted, then I have to step in, and it all goes haywire, even if the mum saw the whole thing (dd will eventually shout "get off!" or "leave me alone!" or something, and is therefore unreasonable .) Should I just abandon all activities?
