Summary:
- Babies are born with over 300 bones, but as they grow, many of these bones fuse together, leaving only 206 bones in the adult human skeleton.
- Newborn babies have a very high percentage of water in their bodies, around 78%, compared to only 60% in adults. This is why babies appear so chubby and soft.
- Babies are born with a natural swimming reflex, allowing them to hold their breath and move their arms and legs in a swimming motion when submerged in water.
