Yes, we pack a backpack with a wallet, camera, video camera, wipes, anti-bacterial wipes and clorox wipes and a couple of diapers. Main supplies are in another bag which stays in stroller. Other bag is monogrammed to discourage someone from stealing. It has a change of clothes for everyone -- adults included, snacks for toddler, more wipes, diapers, sippy cups, plastic utensils for eating, sunscreen, pain meds -- adult and kids-- first aid kit, all other types of medications, such as tummy medicines, etc. Jackets and blankets if it is cooler outside, ponchos for rain, Plastic shower curtain from dollar store to cover stroller if it rains, glow necklaces from dollar store and glow sticks, (saves me money when it gets dark), fan on water bottle (if it's hot), a towel for wiping down stroller if it rains, shout wipes, shout stain stick, footed pj's for daughter if we are staying in the park late, I separate or group items by type and put them in zip loc bags. Makes it easy to find stuff and easy for security. I also have some dishwashing detergent for sippy cups at baby care center and juice boxes. And, extra zip loc bags for putting snacks into for toddler to eat... I'm adding to the bag for the next trip -- plastic drink lids from fast food restaurant -- turn upside down and insert ice cream stick and it stops the drips. I have never (knock on wood) had anything stolen from my stroller.
