Image from the International Hip Dysplasia Institute showing the
importance of using a carrier that places a baby in a seated position,
not hanging by their crotch. There are plenty
of carriers that place baby in the correct position, including but not
limited to Ergo, Boba, Beco, Olives & Applesauce and Babyhawk, as
well as wraps and ring slings when used correctly. Baby Bjorn and
Infantino front packs are of the first type in this image that is not
recommended.
