Baby Carriers differ in the way they distribute weight
Different types of baby carriers have different capability for weight distribution. The more efficient a baby carrier is at weight distribution, the better it will allow a baby wearer to carry heavier babies or toddlers with less effort. The baby slings and pouches score the least in weight distribution comparison because most of the weight is concentrated on a single shoulder. The ergonomic backpack carriers on the other hand, effectively transfers most of the weight to the babywearer's hips, away from the upper body, providing the best weight distribution among baby carriers you can find in the market today.
