Mommy Hospital Bag--this is the best list I've seen. (as a labor nurseI've seen LOTS of families come in with either WAY TOO much crap, or things they don't have that I feel I would want.) This list seems about perfect!
We did this with our 3rd as had no clue about it with our other 2. That's the difference i working with a Doula and midwife! Do your research on all aspects of labor before you just "go with the flow". This is your baby you are bringing into the world! Their health is your priority.
