Someone i know beats their DS a lot, i've seen it once when he annoyed her and our mutual friend has confided it has happenede a fair bit when she has been around and its upsetting to hear. Its because she has postnatal apparantly and he is a very difficult child but still only 2.10 and the same age as mine and i'm not sure i can just ignore it. I've asked my mutual friend to clarify just how hard she is hitting him and she showed me using my sofa and it horrified me as i didn't experience it to that degree and apparantly its repetitive and she gets furthermore annoyed as he doesn't seem to cry which anoys her as she doesn't get a reaction. The whole situation upsets me even thinking about it but what do i do. Shes not actually my friend and the mutual friend doesn't want to get involved...
