Evening. Not sure if this is the right place 
We've been trying to introduce family movie night with 2.3 yo DD but she doesn't have the concentration span for a full length film - with Marmaduke, despite the fact she'd watched the beginning about a million times, she asked to go to bed (!) halfway through and tonight we've watched Toy Story 3 but she got down and started playing halfway through. Not really too bothered (in fact, I'm happy to ignore the lack of concentration thing and just be smug that she's not that interested in telly
) but she was very excited about the idea when we sat down with our bowl of popcorn, so it would be nice to find something we can watch together, even if it's only 30 min or so.
Also out of interest, when do toddlers sit through films? Only ask because I know a few people who take theirs to the cinema so was a bit surprised DD got bored so fast.
