Need some advice on how to handle this. My 7 year old DD who is generally otherwise a fairly calm girl, hit me quite hard today during an argument. She hit me in the ear. Obviously no physical harm done but I was shocked and upset and am quite worried. She was extremely upset and apologetic afterwards and knows she's done something wrong.
It isn't a totally isolated incident but its rare - she went through a phase of hitting when she was 3-4 and this is the first time since then.
Background, if its relevant, is that I'm pretty stressed at the moment. I'm a working single mum, work a lot of the time and it impinges on my life with her quite a lot. I'm separated from her dad and getting divorced, he's in the picture but pretty useless, doesn't pay me any maintenance and doesn't pull his weight with childcare. He has assaulted me once, she didn't witness this but she has heard arguments and is probably aware of tension. In general she's quite sanguine about the fact we're not together (we split when she was just four) and although she occasionally says she misses him etc isn't visibly upset about the fact we don't live together. She sees him regularly and has a good relationship with him and as far as I'm aware he treats her with kindness and respect.
I'm not sure how to handle this: should I talk to the school? to GP? I'm wary of escalating it if its just a developmental stage, don't want to make her feel there's something wrong with her but want to get to the bottom of any issues that may be there. Would really appreciate any advice.
