In the last few weeks my very placid but confident two year old has been the victim of heavy handed tactics from other toddlers at Mums and Tots groups. I'm really frustrated by the Mums of these boistrous tots not really bothering or reprimanding when their kids start to lash out. What is the right thing to do, should I speak to the Mums or let it go (which I have been doing)? Also, if, for example, another tot snatches a toy away from dd, should I take it and give it back to her or just let it happen . . . Help, I'm finding it all really upsetting, am I overreacting?
