I'm very pleased with this bag, it holds way more than I expected it to. Here's what's in it right now. Toddler's shirt, shorts, 3 diapers, sippy cup, small plastic jar of goldfish, applesauce, and fruit leather. Infant's onesie, 4 diapers, bottle, baby food, spoon, 4 formula packets. 3 plastic grocery bags, wallet, a baby blanket, the diaper change pad, wipes, keys, hand sanitizer, water bottle. I also managed to fit in there 2 large folders with their med records and extensive daycare enrollment packets. I've only had it a week but I've used it every day and it's holding up well. The straps are nice, so is the back padding. The stroller straps do their job.
