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. I spent the money on the right carriers and she still got it.....
Hip joint forces promote hip dysplasia in dangling leg style baby carriers.
Baby carriers should support the thigh and allow the legs to spread to prevent hip dysplasia.
Dangling legs in baby carriers may contribute to hip dysplasia.
Baby carrier should support the entire thigh to the knee joint.
