I have two boys, 2.5 yrs and 11 months.

Overall they are both pretty well behaved BUT my two year old has picked up a few bad habits and will just not listen to me.

The 11 month old as babies do - squeals, bites, and is quite a rough baby (and I do attempt to stop the bad habits where I can). My 2 yr old has taken to copying his little brother - biting, squealing, pinching, slapping, spitting etc and I don't know what more to do to get him to stop. How should I handle this? He is constantly biting and spitting at me and his little brother, if his brother squeals, then he squeals louder.

He gets plenty of positive attention from me and my partner and is not excluded at all.
