Yes, kids have kneecaps, but their composition changes significantly during development. While a baby is born with a kneecap structure, it's initially made of cartilage, not bone. This can lead to the misconception that babies are born without kneecaps.
Kneecap Development in Children
- Infancy: At birth, the kneecap (patella) exists as a cartilaginous structure. It resembles a kneecap but isn't yet fully formed as a bone. [Source: Babycenter, Healthline, Parents.com, The Bump]
- Early Childhood (2-6 years): Between the ages of 2 and 6, the cartilaginous patella begins to ossify (turn into bone). A bone center forms within the cartilage. [Source: Rady Children's Hospital, Healthline]
- Childhood and Beyond: The ossification process continues until the kneecap is fully developed as a bone, typically by the time the child reaches their early years. This means that by the time a child is significantly older, their kneecap is fully formed and functions like an adult's. [Source: Healthline]
It's important to note that while infants are born with a kneecap structure made of cartilage, the fully developed bony kneecap seen in adults emerges over time. This explains why some people mistakenly believe babies lack kneecaps. Even with the cartilage kneecap, children can still suffer injuries to the area.

Misconceptions
Many sources clarify the common misconception that babies lack kneecaps at birth. The kneecap is present but is not yet fully ossified into bone.
Conclusion
Children do indeed possess kneecaps; however, these structures undergo significant development, transforming from cartilage to bone over the course of early childhood.
