Wild Child

What to do with a 2.5 year old that constantly is keeping me on my toes. I turn my head his is attacking the baby, I turn around he has taken or hit his older brother. Man oh man.....

All my parenting techniques that were good for the first two do not even touch his approaches to learning. On any given day he tackles a new object, idea, way to get into something, make a bigger mess, attack someone new, rearrange his room, pull all the books out of the bookshelf, oh the list could go on and on. I typically take a deep breath and count to 10 but 20 is more beneficial, now.
