In the last 2 weeks, Ryan has develop this violent behaviour - he throws things around and kicks people.
When he first did it, I already warned him not to do it to me. So, he knows he cannot hit nor kick mummy. But when he gets really upset with me, he will find the nearest wall and start knocking his head on it!!! It was really funny cause he will knock so hard that it is painful and he will start to cry.
Anyway, it is quite a task trying to help him outgrow this behaviour. People around me are suggesting that I spank him, but then he is only 21 months old .... he won't know why we have spanked him anyway. So, I will still try my reasoning approach. So far it has worked very well for me.
Hopefully he will outgrow this phase very quickly.
