I'm a new mom and it always seems like I'm forgetting something when we leave the house. Do you have a checklist for packing a diaper bag?

I always used to keep a bag with all the necessities ready - diaper, wet tissue, 2-3 sets of clothing, towels, powder, bibs, toys, sanitizer, changing bag, cooler bags, spare pastic bags used to pack only the food on the same day - milk bottle, powder, hot water, cereal.
