I fully expect to be told that I am BU here because it's something I see on here a lot...the expectation that SOME toddlers/children will and do hit, bite or attack others as a way of exploring and my favourite..."testing boundaries"
My 2 DDs have never once hit another child. Not once. Why are some more likely to do it than others? THey've got to have seen/learned it somewhere...older siblings maybe who've learned it at school? If so then that is not natural...it's not innate...it's learned.
I don't think it IS natural and I don't think that this is any excuse. I may be deluded oweing to the fact that my two have never hit bitten or in any other way hurt another child but am I really? Mine are ten and seven. I took them to lots of groups etc before they began school and not one time did they hit another toddler.
