Just wanted to post this and maybe gather some opinions on it 
Suppose I'm wondering whether I'm doing the right thing, too, or whether I should be doing more
DD has been friends with a girl in her class since Reception. It seems that since the start of Y2 particularly, they've not been getting on very well (all normal stuff, nothing out of the ordinary IYSWIM - just going in different directions, I think)
But in the last month or so DD has been talking more and more about their arguments and behaviours etc. The teacher also flagged it up as a bit of a concern - something she wants to keep an eye on, anyway. The rows seem to be getting a bit more specific now - DD's friend will shout at her and get cross with her if she plays with others, or won't do as she says. DD has told me that on a couple of occasions she has pushed her and yesterday hit her in the face 
Now, obviously I know that I am only getting DD's side of it. Both are 'strong personalities' and DD can be stroppy and shouty and will (verbally) 'give it back', IYKWIM. So I don't feel she's being bullied, as such, but also don't want my kid getting bashed on a weekly basis either... and don't want DD's assertiveness chipped away at. I don't want her to feel like she is trapped in this dynamic every playtime or whatever
We've talked about different ways to manage her friend, strategies to employ etc. But should I be doing anything else? As I said, teacher is aware
DD seems happy generally, has lots of other friends and enjoys going to school, btw.
That was a bit long, sorry
