Great time to add to this! Thanks everyone. I have a soon to be 2 year old that is no where near the maturity level to understand that he needs to stay on a mat during nap time, but he will soon have to. I'm trying to reconfigure my house so I can start napping the big kids in the play room and I can still chill out in froont of the tv without disturbing them. I have to have something in place by September as I have a 3 year old starting and I want to get the 2 year old conditioned for the sleep mat before the new one comes.

I'm heading to the states this summer on vacation and plan to look at cots. I have 2 mats that the kids us for sleep overs and movie nights, but I think laying on a cot might give them the same feeling as a bed or crib (being off the ground) and might encourage them to stay in it!
