Have you ever looked at a newborn and thought, “How are you so floppy yet so sturdy?” Well, it turns out babies are hiding a secret: they have about 94 more bones than you do.
The Numbers Game
Newborns: approximately 300 bones
Adults: 206 bones
Wait, where do they go?
Don’t worry, they don’t get lost in the diaper genie! Most of a baby’s “skeleton” is actually made of cartilage (the same flexible stuff your ears and nose are made of). As babies grow, a process called ossification happens. Those smaller pieces of cartilage fuse together to create larger, stronger bones.
The “Squishy” Benefit
There is a brilliant reason for this design:
The Great Escape: Being “bone-lite” and mostly cartilage makes the birth process possible.
Growth Spurts: They allow for the rapid, massive growth that occurs in the first few years of life.
💡 Tip for Parents
This is also why babies don’t have “bony” kneecaps yet! If you feel a baby’s knee, it’s just a soft little nugget of cartilage. Their actual kneecaps don’t fully harden into bone until they are between 3 and 5 years old.

Questions People Ask
If babies have more bones, why are they so fragile?
It’s actually the opposite! Because their “bones” are mostly flexible cartilage, babies are surprisingly resilient. Their skeletons can bend and absorb impact more easily than adult bones, which are more brittle and prone to snapping. However, babies’ internal organs and brain are still very delicate, which is why we handle them with such care.
When does the “fusing” process finish?
Most of the major fusing happens during childhood, but the human skeleton isn’t “finished” until your mid-twenties. The last bone to fully fuse is usually the collarbone (clavicle).
What is the “soft spot” on a baby’s head?
These are called fontanelles. They are gaps where the skull bones haven’t fused yet. They allow the head to compress during birth and give the brain plenty of room to grow rapidly during the first year.
Why do some babies lose their hair after birth?
It’s a hormone thing! After birth, a baby’s hormone levels drop, which can cause their hair to enter a “resting phase” and fall out. Don’t worry—the permanent “big kid” hair usually starts growing back in within a few months.
Can babies see clearly when they are born?
Not quite. Newborns are very nearsighted. They can only see clearly about 8 to 12 inches away which, coincidentally, is the exact distance to their parent’s face while being held or fed. They also prefer high-contrast patterns (black and white) because their colour vision is still “booting up.”
