My DD2 is 6 and in year 1. I think her best friend (let's call her Emma) has a bad influence over her. She's always been bossy, and excludes girls that she's fallen out with. DD2 has been on the receiving end of this in the past, but she has enough other friends for this not to be a problem for her.
But recently she's gone further. She told DD2 to bite herself on the arm and tell the teacher that another friend had bitten her. She said that DD2 wouldn't be her best friend anymore if she didn't do it. So DD2 did what she told her.
In DD2's defence, she told me about it at home time. I told her off, of course, she said she did it because she didn't want Emma to stop being her best friend.
In the past Emma has told DD2 to slap her big sister on the bottom. I don't think DD1 (9) actually minded, but it's another example of the way DD2 seems to be unable to say no to her. It's as if when Emma tells her to jump she asks, 'How high?'
It's baffling because DD2 is popular and feisty and has a mind of her own, so I can't understand why she's so unable to say no to her. (She's not the only one, though, tbf.)
The school has a double intake (2 classes in each year) and they do mix up the classes at the end of year, so I'm wondering if we should suggest to the school that it would be a good idea to separate them?
