Okay I'm totally clueless about this!

LO is starting daycare in about 2 weeks (holy crap....but that's a different post!) when she turns 6 months and I realized I probably need to put something on her feet when she's there! She usually goes barefoot at home because it's been hot anyway and socks are a pain to put on and fall off so quickly...but it's getting cooler out and she won't be home all day anymore.

What does/did/will you put on your babe's footsies when He/she/they were around this age? Just socks? Or some kind of shoe/bootie? If so, what are your favorites?
