- Diapers: Follow the rule of always bringing a few more than you think you'll need.
- Wipes: Stock up on travel-sized packages so that you'll always have some ready to go.
- Diaper Cream: Save any sample-size tubes that you get from the pediatrician or baby store, and keep them in your bag.
- Changing Pad: Most diaper bags come with them, so only purchase an extra if it's necessary.
- Change of Clothes: You never know when a diaper's going to explode or spit-up's going to become a mess.
- Sealable Plastic Bags: These become trash bags in a pinch.
- Bottle, Formula, or Snacks: Pack accordingly, depending on the length (or potential length) of your outing.
- Bottled Water: For you to drink, to use with powdered formula, or to rinse off any other surprises that may come your way.
- First Aid Kit: It can never hurt to be prepared . . .
- Toys and Other Distractions: You know your baby best! If there's a go-to stuffed animal or "lovey" that he or she can't live without, bump this up to the "necessities" category.
- Sling or Wrap: If your baby prefers to be carried, this may save tears when you arrive at your destination.
- Blanket: To serve as a shade, nursing cover, changing pad, or burp cloth in a pinch.
- Hand Sanitizer: If you're looking to streamline, wipes can do double-duty here. Otherwise, a little bottle doesn't take up much room.
