I've been hearing that there are many experts that are against giving toddlers and iPad to play with. I'm sure that if you let them spend hours and hours with it, it will be bad for them, however, I'm not sure what is the harm in letting them play with age appropriate toddler apps like (such as the BBC's teletubbies) for 15-30 minutes a day.
Am i missing something? is there a negative influence i'm not aware of?
