Usually I'm carrying a change pad, 4 diapers, a travel wipes case, an extra onesie, a burp cloth, 2 pacifiers, 2 bottles, a travel formula container, a small toy, teething crackers, and a baggie of cheerios. My son is 10 months old. We keep it simple at our house. :)
diapers, wipes, diaper rash cream, teething rings, bibs, extra change of clothes, receiving blankets, extra bottles, formula (breast milk in bottles) a soft bristle comb, something to distract him (toys), pacifiers.
I have an extra outfit, a travel formula container, one bottle, extra bib, extra burp cloth, a snack, some oatmeal, bottle of water, powder, toys, travel wipe case, changing pad that has zippers for diapers and wipes, 10 diapers, the food she's eating for the day, Tylenol, a munchkin container that she can eat fruit with, and some tops that can turn a regular water bottle into a baby bottle. When she gets older I can carry around some actual snacks for her (and me) but she's too little now.
I think a cell phone charger is important to throw in there, even if you have one in your car. That one time you grab your bag and run will be the day you didnt take your car, NEED to get in touch with a family member and have a dead phone in your bag. Its so light, you can just toss it in a pocket and forget til you need it.
