I've just been having a look at Totlol. Totlol describes itself as; "a brand new community-moderated video website designed to be enjoyed by those between the ages of 6 months and 6 years."
It's actually a really nice place to find andd share video clips which are appropriate for young learners to use. Great place to tip parents off about too, so that they can enjoy some entertaining clips with their kids.
Hope you enjoy this. http://www.totlol.com/
