The question is, how does your back feel? I was hauling around a baby and the bag. I had always been very active and played in may sports when I was younger, injuries unavoidable. Well after gaining the breasts to feed an army, sometimes carrying the baby and the bag, my back was aching. My doctor recommended a back pack. This distributees the weight, will not affect your posture and I found more durable. They now come in so many great patterns with so many compartments, it doesn't necessarily need to be specific to Baby. Daddies then also do not have issues carrying. Also when shopping, I found them easier to attach to carts and strollers, without occupying space and easily more accessible. Also, I could throw it in the washing machine!!
