HELP - 2 under 2 naptime dilemma

[Dreamalittledream]

When I have to run upstairs quickly (bathroom etc.); I place my under 2's in their booster seat (with tray locked in). This way, I know they are safe/contained & entertained (book/toy/puzzle in hand) for the minute I am gone. I also have a video monitor to watch the rest of the group. For me, I just cannot take the time (for the safety of the rest of the group) to rock/bottle/soothe a child to sleep at nap time, so I make sure @ interview time that the child is able to self soothe to sleep.
