My DS is very nearly 3yo, my DD is 8 months old.
DS keeps hurting her. He struggled with jealousy when she was born, I acknowledged this. In some respects his behaviour is better, but in some it's much worse.
I can't leave DD alone with DS, not even for a minute, because he will hurt her. He will sit on her, lie on her, hit her, kick her, throw things at her, stand on her...he just seems to enjoy it.
I guess I'm looking for any advice or ideas; what can I do?
