Twice now I've gotten a big box of hand me down clothes and I end up only keeping half of the box. My LO just has so many clothes (all gifted and hand me downs, I don't buy her anything!) so I don't really need all of it and I'll just go through and keep the things I like best and think she needs. There are some winter things that I don't love that I'm keeping, but that's because we don't have a lot of winter things and I'm too cheap to go out and buy my own when it's right here for free.
Still, I feel weird not using the other stuff because it's free too.
