Baby clothes

Recently I was given a big box, a tub and bag of used baby clothes. I have a handful of new outfits from my mom and family and haven't had a baby shower yet. Some of these clothes have drool/food stains but not bad. There are some that I'm going to donate because they are not the right season. I'm wondering how picky I should/can be? I have no problem with being used and slightly stained but some of my drawers are very full. Should I keep them all and dedicate a new drawer? Or donate some of them? Specifically how many sleepers will I need (3-6 & 6-9 months)?
