cat paw is correct Babies are NOT born with knee caps they form around two years of age. Also babies are actually born with more bones than an adult they have 4 extra forming their skull so that the baby can pass through the birth canal (soft spot) my mom is radiological tech. that's where i learned this stuff from.
FYI for all that do not know that cartilage is NOT BONE so there for babies are not BORN with knee caps knee caps are bones and is actually called a Patella

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.
Remember, infants are a work in progress. The potential for linear bone growth may continue until the late teens or early twenties. Although all the precursor tissues for the major bones are present at or immediately after birth, centers of ossification (where bone is laid down) continue to develop throughout childhood and beyond. For instance, the head of the femur appears at four months, the patella, or kneecap, starts showing signs of ossification at about 3 years in females and 4-5 years of age in males. Parts of the pelvic girdle (hips) don’t appear ossified until adolescence with the tubercle of the pubis not appearing until 18-20 years of age.
So yes babies have kneecaps from about 4 months they are just not harden like ours are at that stage.

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.

Babies are normally born with kneecaps. Kneecaps only start to turn bony (ossify) at 3 years of age, before that they are made of cartilage.
There is a condition known as 'Nail Patella Syndrome' where a baby could be born without kneecaps.

yeah, babies have all the bones that you do. they are much softer -especially kneecaps which i believe may be made of cartilage at first? but aside from a defect they should have them all.

Yes, unless they have some sort of congenital deformity
