Sigh. I have a lovely neighbor who I've become good friends with. She has 2 DDs, I have 2 DDs, it's been a good relationship up til the last few months.
Her DD1 (A) has gotten really aggressive. She is 2.9 and her behaviour is age-appropriate but oh my goodness it's unpleasant!! My DD1 is in school so I mostly see her with DD2 in tow. DD2 is 2.1 (only 8mos between them but it makes a big difference at this stage) and A just terrorizes her. DD2 is small for her age and A is big for hers (bigger than my 4yo) and A's language is very advanced so she thinks of DD2 as a baby. She's always yanking toys off DD2 and saying "she can't have that because she's a BABY" which as you can imagine hits DD2 in 2 places.
I never invite them over anymore because A is then mean to DD2 in her own house, taking her own toys off her and shoving her around and I can't tell my neighbor "your daughter is being really unkind, please leave." So we go over to theirs and invariably end up leaving after A has pushed DD2 to the ground and then spat at her, although after that incident I'm not taking DD2 over there anymore.
What bugs me the most is that my friend doesn't do anything about it. A will take something off DD2 and her mum will tell her to get something to trade. Fine with babies, not with 2 year olds who are usually playing with a specific toy for a reason. A is very rough and there are no consequences, with the shoving incident her mum put her on the naughty spot as we left but you could tell that it wasn't a regular occurence, that A had no idea that her behaviour was unacceptable.
Anyway, just ranting really. Have had to decline an invitation today as I just can't stand it anymore even though I'd love to have a cup of tea and a chat! Said I didn't think the girls were very happy to play together as you can't say we'll only come over if you shadow your daughter the whole time and stop her being awful to mine. Have made plans for drinks without children instead!
