It's hard to know. We're about to take the gamble with our 2 1/2 year old. My niece went a few months ago, before she turned 3, and sat through the entire movie, but she will happily watch movies at home too. My DD will sit though a 40 minute play school or Wiggles DVD, but we haven't yet found a movie for home that she'll sit thorugh. She's very interested in Smurfs though, so we thought we'd give it a go with her. Good luck!
