We love to carry our baby using different baby wearing products...baby carrier (baby bjorn, ergo baby, etc.), the sling (with adjustable rings), etc.
Depending on the age, they will generally be worn in different positions. Generally when their infants their entire lower body is inside and their legs are folded in all sorts of ways. When they are a little older, their legs are kind of spread and straddle the parent's body (or if their facing out they don't straddle anything).
My question is that because they are in these positions for, cumulatively, long periods of time, will this have an effect on their hips, or leg joints, etc.?
