Went to M&T group today. Ds got hit and shoved by one child who wanted to get into the Little Tykes car ds was in. And then had his hair pulled very badly by another child who wanted to play with the toy kitchen - there was enough room for both of them but that wasn't enough apparently. Hair pulling child grabbed two chunks of poor ds's hair and wouldn't let go! Had to drag him off ds. Both parents were apologetic when they saw me telling their kids off (calmly and politely) and made them say sorry - but is there anything I can do to help ds when other children are harrassing him? I know they probably all do this at some stage but ds has never done more than tried to grab another toy at the same time - doesn't pull hair or manhandle other kids. He's 2, btw. One of the kids was older, one of them looked a bit younger.
Any advice welcomed. TIA.
