I have the original bag, and it’s just too big for us. The Mini Classic II bag is the perfect size for us, for baby #3. How often do you really use your diaper bag contents while at the mall or grocery shopping? Rarely. I prefer to pack light, and include a warm out, a short sleeve outfit, a thin jacket, an extra pair of socks, two bibs, 5 diapers in the pouch, and a thin case of baby wipes. Sometimes I will roll up a swaddle and also throw it in there.
