Think I need advice as to how to handle this as much as whether IABU.
This toddler kicks, hits and shoves kids that are smaller than herself, including my DS given half the chance. I work in a creche as a volunteer and I dread it when her mother brings her in as I know that myself and the other volunteers will spend much of the session trying to protect the youngest one present as they seem to be the focus of her aggression. We do make a point of giving her praise and attention when she is playing nicely, but the bad behaviour cannot be ignored as we cannot allow her to hurt other peoples' children. If she manages to hit, kick or shove another child, we focus the attention on comforting the child that was attacked.
Her mother has watched her DD hitting other kids, and once shoving then jumping on top of a child causing him to bang his head badly on a hard floor, but she never reprimands her in any way or apologises. I have heard her say, 'Oh it was just an accident'when it wasn't, although to be fair, this child's behaviour is even more agressive when her mum isn't in the room. If my DS does anything like that to another child, I make it clear to him that behavior like that is not acceptable, and I usually apologise to the child's parent or carer.
I tentatively raised the issue with the child's mum and she acknowledged that her DD had ' a bit of a problem with hitting at the moment, but it is just a phase' and she didn't want to discuss it further.
I don't want to bar this child from the creche, as she is basically a sweet kid that needs some discipline, but some of the creche volunteers are fed up, and I think some of the other parents would be too if they knew. And I don't want other kids to dread coming to the creche because of her - we try so hard to make it a nice experience for them.
So how can I get through to her mum? I feel as though I'm running out of options.
