It's hard isn't it? Because my son can't yet speak (just turned one two days ago!) he throws things when he's upset. For example at mealtime... "I'm done with my drink" = throwing the sippy... "I don't want anymore/I don't like it" = throwing/shoving the plate... "don't look at me that way" = throwing whatever he can get his hands on first. And he does this with a scowl on his face and sometimes an angry cry too.
If you happen to be holding him (or in the midst of picking him up) when he's not happy well, then comes the back arching! Oh, look out!
It's really frustrating! At the moment it's really coming out at mealtimes. I want to just finish the meal and take him away... and yet I'm worried he won't get enough to eat. :(
I know he must be terribly frustrated not being able to communicate better, and I feel for him and want to help him...BUT he also needs to learn to control himself a little... right??? aaak! This is hard to know what to do!
