Bag prep for childbirth

A picture ID (driver's license or passport), your insurance card, and any hospital paperwork

Your birth plan (if you made one)

Eyeglasses, if you wear them. Wear these instead of contact lenses, too. Much easier for this moment.

A bathrobe, nightgown (or 2?), slippers, and cozy socks

Items from home that help you relax - favorite pillow, some music to play, a book you love, etc.

A camera or video camera with all necessary power equipment (batteries, charger, memory card)

Toiletries

Comfy shoes

A change of regular clothes

Snacks

Money (credit card, cash, and quarters) for things like parking and vending machines

A bathing suit in case you would like to take a bath or shower during your hours of labor

Both nursing bras and regular bras - weather or not you breast feed, the breast will be tender and enlarged when the milk forms, so bras are necessary for comfort

Multiple pairs of maternity pants (ones with a spandex or mesh waist bands)

Any books you intend to read specifically on newborn care

Gifts for older siblings

A notepad/journal and a pen/paper if you wish to write down thoughts or parts of your experience

A "returning home" outfit

A pre-installed baby carseat

A "returning home" outfit for the newborn

A "receiving" blanket to swaddle the newborn
