Babies are the cutest living things that are alive on the planet. They cry, they poop, deprive you of sleep, yet they mean the world to the parents. Babies when start to crawl, walk or stand, they tend to fall frequently because they hardly know how to balance themselves on their feet. But as parents you would have wondered, despite of falling many times they don’t have broken a bone. So what is the reason behind it? These are some answers that parents are always looking for.
Why don’t babies have broken bones when they fall?
We all know that baby’s bones are very soft till first year of their birth. But then arises another question, do baby have kneecaps? Of course, babies are born with kneecaps; however they are much softer than of adults. The bone structure of the baby and the adult is absolutely same; but are softer in their adolescent years, yet strong enough to support their bodies. The bone structure of the baby consists of immature bones and cartilages that develop as they grow old. By the time they reach adulthood, the bones are fully formed and acquire strength.
The development of the kneecap
So after reading the above paragraph, it answers the question about do baby have kneecaps when born? Now let us know how these kneecaps are developed.
Babies are born with kneecaps but are made up of soft cartilage tissue. Over a period of time, these soft cartilages take form of bones through a process known as ossification. A layer of cells is formed on the skirting of the cartilage and produce a compact bone. Then the blood vessels are formed near and around the cartilage thereby forming a nutrient artery that helps in bone development. As the baby grows, the ossification process continues to produce bone cells that replace the cartilage with new bones.
Even though the process of ossification is performed, still the cartilage in the kneecaps remains for few years. That is the reason you must have babies don’t break their knees when they fall. These soft cartilages act as sponges that can easily absorb the pressure and compress when baby falls. It is after 3 years that baby’s bones start developing through the ossification process.
It is quite understandable that babies do have kneecaps but they don’t have bone in their kneecap. One very good explanation could be, if the babies have bones in their kneecaps then they it might pain when the baby starts crawling. It is because of soft cartilage that is able to take the pressure on the knees.
