Big stuff or little
Divide the behaviors into the "big stuff" and the "little stuff".
Big stuff are those things that are not negotiable- hitting, biting, throwing things, dangerous things. Pick up your child and put him in time out (1 minute for age). Little stuff are the things that aren't that big, but you'd rather he didn't do. Distract his attention, move him to a new activity. Try not to say "no" all day.
