In all ergonomic carrier backpacks, babies can only be carried in the position facing their mother (i.e., it is impossible to seat the child with their back to their mother). Unlike traditional kangaroo bags, the ergonomic backpack provides the baby with a physiologically correct posture with widely spread legs: a physiological M-position recommended by orthopedists, in which the load falls not on the baby's crotch, but is evenly distributed on the hips, butt and back. The child, as it were, merges with the mother into a single whole, the legs hug the mother on the sides and do not interfere with the mother when walking.
