• I would suggest getting the large so that you have plenty of room if not some extra in case you need to place something unexpected in it.

  • Would say you'd need the large if your carrying the kids things as well. The medium bags hold a fair amount - full size wallet, phone, small make-up bag, and even a water bottle due to the height of the bag. There are lots of little compartments for keys, tissues, nail nippers,etc.|However, I would asume you are carrying wipes, sippy cups, a toy or two, crayons, and the like? If so then go with the large bag. It will hold everyone's stuff and still have the same design features. |The bags really are comfortable. My physical therapist talked me into getting mine. |Hope this helps.
