I agree with the previous posters, tightlycurly is an excellent resource. Here is the link you want:

Full color photos, step-by-step on how to painlessly detangle, de-frizz, and maintain a child's curls.

The key 'take-home message' is, use conditioner, and use lots of it. Leave it in, don't rinse it out. As tightlycurly says, "Ignore what the bottle says. That's for wimpy hair. Your hair is not wimpy!"
