Babies are not born with kneecaps.
A patella is a sesamoid bone that develops from the pressure caused by habitual walking. Most of the time, the patella appears at about 2 years of age. If a child has a developmental defect and is never able to walk, he/she will never develop a kneecap.
Many bones are not developmentally complete at birth. Most people know about the skull and the "soft spots," but that's just one example. Long bones (in the arms and legs) are formed by a cartilage anlagen that slowly ossifies - but a "growth plate" of cartilage remains at each end of the long bone until the end of adolescence. Each vertebra is in three pieces at birth.

No babies don't have knee caps at birth, their legs are still quite drawn up towards their bodies for firest few weeks and then knee caps develop by ^ months of age.

All posted above me are wrong, babies are NOT born with knee caps, if they were they would be able to support themselves on their own legs much sooner. They actually begin to develop later on. They begin are a form of cartilage.

The patella ossifies between the ages 2-6 years. In some people it may be absent congenitally or hypoplastic. In 2% of the population there is a bipartite patella, which is usually asymptomatic.

Yes of course .
.Newborns do have kneecaps . Kneecaps form about the fourth month of fetal life. However, they don’t show up on x-ray very well because they’re not ossified, or bony. At this point in life, the kneecaps are made of a cartilaginous material. The growth centers surrounding the kneecap form late in developmental life in utero and may not appear until just before or just after the infant is born.

Yes babies are born with kneecaps.
It is their muscles that have to develop further for the purposes of crawling and walking - after all their little limbs are brand new and have never been used before.
