I come from the other side of the glass. My toddlers have iPads and constantly tap ads that are usually larger than real, in-app actions. Often the ads are interstitial between two game screens, or float next to the content they are interested in. Besides being frustrating for the kids, I have to be vigilant on the content of the ads they're seeing. From my experience, the ads are not always appropriate for kids. I really wish Apple would offer a "No Ads in Kids Apps" policy.
