Depends if you're going to use ot for just baby things, or your things as well. For me I'm using it for her things only and will still carry my purse. So what I have in mine; 2 thick fleece blankets, 4 thin blankets for eother burping or as a lighter cover. 2 socks and 1 thicker fleece sock. Diapers, wipes in a traveling case, A&D cream (butt cream), baby sunscrean, ziplock baggy of travelsized shampoo, lotion, baby powder, and oil. Nursing cover, and ziplock baggie of nursing pads. Change of clothes will be added accordingly.
