DS is 18 months. In the last few weeks he has starting headbutting me and other things, so badly he has a bruise in the centre of his forehead. He doesn't seem bothered by it.
He has also started hitting out at me, and sometimes he actually hurts.
A firm "no" gets a chuckle or a grin from him. If I say "ow" he laughs. I think he is too young for the naughty step.
Why is he doing it and what can I do?
Thanks o wise ones.
