I have been thinking about this a lot and would like to get some other opinions. I have 2 DDs, 6yo & 4yo. DD6 has a friend who is creative, clever and interesting. She can be really good fun to have around as she is interested in everything. However, she and DD6 sometimes torment DD4--not just teasing, they scream at her and throw things (friend is quite inventive with her tortures).
DD6 does not behave this way when friend isn't around. With other friends, they either ignore DD4 or do much more mild teasing or chase games (sometimes they even all play together!) DD6 & DD4 squabble plenty, neither is an angel but friend just seems to add an element of meanness to the equation.
I have spoken to friend's dad (main carer) and he is of the opinion that although tormenting younger siblings is not acceptable and children must be told off for it, there is no way to stop it happening as it is a natural part of family life. I agree with this to an extent but there is a level of unkindness that was never there in my own family, and that DD6 does not have when friend is not there. I have spoken to and sanctioned DD6 many times for this behaviour but it just doesn't stop.
So AIBU to just not have friend over again? Her dad thinks I am--he seems to think that it's DD4's lot in life to put up with it (he has seen DD6 & friend at their worst). I think she shouldn't have to.
