I was at a birthday party today and DS showed me a beetle that was on the bouncy castle. He was really interested and we were talking about it and other insects when another little boy (aged 4) just walked up looked at it and then stamped on it about 5 times. I know it sounds silly but it shocked me mainly I think because neither of my DC would dream of doing such a thing. Do many kids do this sort of thing? He also shoved my 20 month old DD over for no particular reason. Obviously I gave him the full on mummy glare but have been wondering since if this is just what kids do and maybe mine are a bit too wrapped in cotton wool.
