Melanie,
My first response was: what exactly is this site for? It looks a bit too much like one of those sites where people just post a bunch of advertising. Granted, I don't have small children at home, but I'm wondering if it might help to have more of an introduction to what the site is for. What is your mission? If it is to help parents have successful parties? Is it just a store for cartoon products? I guess my response is that I couldn't figure out why I would want to go beyond the first page because I couldn't figure out what your mission was. . .so I wasn't sure how it would be of value to me.
I hope this helps. I'm not trying to be discouraging because, if I can guess what you are trying to do, I think it is an interesting concept. But you might want to add sections on pary ideas - say, how to put together a Bratz themed party or a Superman themed party. Decorating tips for cakes, etc. Of course, that may not really be your mission, but you need something to let your reader know what they are supposed to do Lead them to the next step somehow.
