diaper bags: I can stash so much stuff in one of those! Snack for baby, snack for me. Drink for baby, drink for me. Diapers of course. My wallet. nail clipper.
strollers: sort of like the diaper bag, you can stash so much stuff in it!
empty baby food jars: pill bottle, salad dressing to work, freezing your own baby food in, fresh chopped garlic.
