Okay, long back story here:
My DD is now 2 1/2, and we live very close to a friend who also has a child of almost exactly the same age. Ever since Other Child was able to crawl, she has always been dominant of my DD. This was fine when they were babies, when it amounted to pointless toy pinching, but as they have grown older the behaviour of Other Child has not just remained bad, but has gotten worse. She repeatedly throws enormous temper tantrums over the slightest thing. They are very regular, very screamy, and very disruptive. Other Child does not have particularly advanced language skills. Probably about average for her age, so I have put a lot of the tantrums down to being unable to express herself. She has also chosen to accompany her tantrums with acts of physical violence, and whenever we are with her, these acts of violence are almost always directed towards my DD. Worse, even when she's not tantruming, Other Child is still overly dominating of my DD, to the point where if they both walk into a play group together and DD picks up a toy (and there are a thousand other toys to choose from) Other Child has eyes only for the toy my DD is holding, and will happily hurt her to get it. She then repeats this pattern throughout every single play date, regardless of location or quantity of toys. To say the least it is tiresome. I am going to come across as a pompous arse here, but DD is much better at speaking than Other Child. She also understands much more of the world around her than Other Child, so when Other Child keeps pinching her toys, hurting her, pushing her, DD knows to just come and calmly tell an adult. So me and my friend spend inordinate amounts of time trying to calm Other Child down and rectify the situation. The thing is, my friend is incredibly defensive of Other Child's behaviour, constantly defending or excusing her actions (she doesn't know what she's doing, she's just so passionate about things, she's tired, etc). I am being bullshitted by a friend who cannot be bothered to discipline her child correctly, but worse than that my child is being made to feel that this behaviour is acceptable, and should be treated as a fact of life. My friend and I had always just said to one another that Other Child would grow out of it, that it was just a phase, that we ought to keep socialising our daughters until it all blew over. But the other day, the final straw came for me: when on the road en route to a play group I drive my friend and Other Child to, along with DD and DS (7mo), Other Child bit DD so hard she screamed in pain. Undaunted by her mothers' feeble telling off, she proceeded to do it over and over again. I was driving and could do nothing.
My question is, what would you do?
Cut off all contact with DD and Other Child?
Demand my friend pays proper attention, and more effectively disciplines her brat (and I DO NOT mean smacking)?
Ignore it and hope it all goes away?
I am at my wits end trying to figure out how to progress with this. For the last week, I have been 'busy' whenever my friend has suggested we meet up because I cannot stand the sight of Other Child. Today, we bumped into them for two minutes. What did Other Child do? Immediately lashed out at DD for no other reason than (according to her mother) she was tired.
Also, my friend, who is a very dear friend to me, has absolutely no help whatsoever at all at home, is effectively a single mother without even her family to support her as they all live overseas, and suffers with depression. The last thing I want is to make things difficult for, or isolate, my friend for the sake of her child's behaviour.
Thanks for reading this far, and I am sorry it has taken so long to get this out.
