He is precious! Enjoy the helpful stage while you can. My seven year old complains about having to do anything, and he to used to want to help with everything. Fortunately I have a 3 year old to pick up the slack for now
My two year old and my 4 year old are very competitive with each other. It doesn't take much to get both of them going in an effort to outdo each other. We try to make a game or a competition out of almost everything we do. The really cool thing is that even with all of the competition, the two of them are very close.
