This morning I took DD (2.5) to church as normal. The kids all play together after the service and normally it's really nice opportunity for different ages to play together.
Today another girl (4) was pushing and shoving DD. The Mum intervened and DD was ok so I didn't think anything of it. But then, outside the kids were playing on the grass, the other Mum was deep in conversation with someone else and the other little girl started on DD again - she got in several shoves, a hit and had pulled her down to the ground by the time I got to them. I removed DD who was howling, comforted her and we left to walk home - I was upset and didn't know what to say/do. The other Mum was oblivious and just kept talking.
I'm not sure now whether to say/do something or not. The other Mum is having a tough time so I don't want to upset her. The 4yo is autistic so I know that affects her behaviour but I don't want my DD to think that it's ok to push, hit etc.
