If you're not already a member of Ravelry, you should join. A great community, and a wonderful source of patterns. Also, your local public library will have lots of crochet books of various kinds. Look into it!!

http://www.crochetpatterncentral.com/This site is a comprehensive set of links to other sites. http://seafore.8m.com/This is a mirror of the original seafore.com website. It's got links to other sites but has not been updated or maintained recently (the previous webmaster passed away). There may be some old/dead links as a result.http://www.berroco.com/item_fr/fr_crochet.htmlThis is the list of free crochet patterns from yarn maker Berroco. They have more knit patterns than crochet, but I do really love their patterns. Trendier patterns and different from the ordinary stuff you see.http://www.lionbrand.comThis one is from Lion Brand Yarn. You'll need to become a member (free) to view their patterns.Those are just a few. You can check different yarn manufacturer websites to see if they have patterns.-Stephanie
I forgot to mention that Berroco doesn't really have any kids' patterns. But, if you are a good crocheter, you can scale it. Or use it as an inspiration/starting point.
