Hi my ds is 22 months and is a very loving boy sometimes. he does gives kisses and cuddles but he has turned nasty, he hits and pinches and now punches. and he pulls hair. he does it to strange adults at toddler group too. He doesnt do it to children except his dss but he has just turned devisish. he started headbutting people to but he doesnt do that as much anymore. Why is he doing it, he doesnt see any violence at home ok he hears me telling off the girls but we dont hit or smack at all. My dd was never like this. I am always giving him attention so he isnt crying out for love. i just dont know what to do anymore, i feel like im doing something wrong
