Playfelt...do you mean that you have a room set up where all the children sleep? I would LOVE To put two kids on rest mats in the same room but I am worried they would never stay put.
Also...you have children sleeping on a rest mat in the playroom? How do you ensure they don't get up and play? I use a playard in the playroom nap area but am scared that putting a nap mat would mean that the temptation to play with all the toys in the toy room would be too great.
