My 2yo DD is starting daycare in a couple of weeks, and we need to provide shoes she will only wear indoors. What does everyone else do? Montessori Movers? Skidders? Crocheted slippers from Etsy?

I know I also have to consider that occasionally there will be fire drills (or God forbid, a real fire) when she won't have time to put on her outdoor shoes, so should I just get her some sneakers? Help!
