Ask HN: Is iAds publishing right for me?

Hi guys,

I'm just about ready to launch my iPad app, its basically a drag and drop thing for kids to play around with.

This is my first app so the intention was just to get around to learning development and getting on the app market. So I'll probably release the app for free and just see how it does.

However, I was wondering if it would be worthwhile to add advertising to it. Is the return on iAds/other advertising agents good? Considering its an app for kids, is sticking banner ads on a bad idea?

Thanks
