Your question raises several questions in my mind. A good response would review appropriate skills for your child's developmental age. In lieu of this, I've attached several web sites that provide good information. If these sites don't seem to answer all your questions after reading them, take a look at the numerous, wonderful articles on the Education.com site by clicking on "Education A-Z." In the top left of your screen, you will see the "Search" bar. Just type in key words for the items you're interested in, ex. "sit still." Several articles will pop-up for you.

Happy reading!
