We've been letting LO go diaper free on the weekends. I can't count how many times she has peed on the floor and then looks at us like we are the crazy ones. It's also a little cold, so I am thinking of buying training pants for home and some kind of pull-up for M-F when she's at the nanny share. She pulls off her diaper all the time now, so something that is also easy to get off without taking off her pants.
We use Pampers Swaddlers size 5 right now.
