Recently I picked up a package of small 2"x3" zipper bags at Wal-Mart in the craft section (100 bags for $1.00). I love them!
I love using them for holding snacks for my kids. They are nice and small and fit well in my purse. I was grateful I had them yesterday at the grocery store when my 1-year old began melting down at the end of our trip.
You've seen these fruit snacks at Costco. Each bag has 2.5 servings or so. I divided them up into the little bags- perfect for kids.
I think I got about 10 snacks in this quart-sized bag with plenty of space for more. I keep this in my purse.
Snacks that fit well:
mini marshmallows (marshmallow bits are even better)
M&Ms or other small candy
raisins (instead of buying those little boxes that cost so much money)
I will definitely put these in my kids' lunch boxes when they get older.
