If you have kids, you just found the site you have been looking for.
Totlol is a video website designed specifically for children. It is community moderated. It is constantly growing. It is powered by YouTube.
All videos were submitted, screened and rated by parents. The selection is huge and if you like, you can participate too.
Totlol is literally Video-on-Demand, and if you have kids, you already know. The video part is easy. It is the demand part that is hard.
