RE: What's a
I use the Little Tripper if I'm going to be gone for 1 hour or less. Like going to the grocery store for a handful of items, the post office, etc. When you'll need some baby stuff just in case (so I don't just use a purse), but not alot of stuff. There has never been a time when I was out for an hour or less that I needed a diaper, but I have always needed a snack or toy to keep DS from fussing. Also, burp cloths are a MUST. I'd say in a LT put 2 diapers, and keep some extra in your car for back ups.
For bigger bags, I use them when I'm out for several hours at the mall, running errands, at a friends house, etc. I'd keep 4 diapers in your bag for those times.
I have a tote bag in my car with:
6 diapers
extra wipes pack
used to have some Similac Singles of formula, a bottle of water, and a clean bottle in a ziplock when DS was small. Now it's some Gerber individual juice bottles and a sippy cup
Snacks for DS in sealed containers
Lightweight jacket
handiwipes
Couple of toys
Small blanket (could be used for a changing pad if need be).
Every once in awhile I run out of stuff in my diaper bag, and I have somehow actually forgotten the diaper twice! and these back up supplies came in very handy.
When I have more time, I'll post a list of what's in my Quick Trip bag, versus my longer-day bag.
