are human bones bendy

Human bones, in general, are not bendy, but this mainly depends on which bones and at what age of life.
At birth, a baby has soft spots on its head, called fontanels. These soft spots were squeezed to form the head shape (if the child was born vaginally, not by cesarean section). As the baby ages, these soft spots turn into hard bone to form the skull and its layers (pia mater, dura mater).
As for other bones of the body, they are not bendy. Rather, they are connected by joints, which allows us to move our body in many different ways.
I believe, though, there is a disorder that can cause people to be extra flexible. It is called Eller Denlaw's disease (mid the spelling, i heard the disease on the health channel), and it can be life-threatening and somewhat beneficial. It gives the victim nearly unlimited mobility, but it can cause major bone dislocation.
Hope this helps!

Yes, they are a little bit "bendy," but don't get over-confident. Most of them break more easily than they bend.

There are some notable flexible parts, like the cartilage in your nose, which you can wiggle. But that can also be broken or broken loose from the adjoining bone. It's a really odd look, that is not fashionable any more.

Small babies have bones that are much more flexible (bendy) than adult bones, but they get stiffer as the baby grows up.

All human bones start out as cartilage in the womb, so fetal bones are extremely flexible. As a person ages, the living bone cells inside each bone replace the cartilage with calcium carbonate, making them much less flexible. That doesn't mean they are completely brittle, but they do break more easily as a person ages.

Yes, there is a small amount of bending, but not much. It is present much more in small children than adults. In fact this is why it is possible for a baby to fit through a woman's pelvis, it's skull can squish in slightly and then bend back to normal state. Hope this helps!

That depends on which stage of life that you're talking about. Infants are born with flexible bones (they have to bend to make it through the birth canal). After that, bones harden and may flex slightly as they absorb and disperse stress that is placed on them but they don't "bend".

Technically yes, a very small amount but yes they can bend.

Childrens bones can bend more than adults, but even adults bones can bend a little, I'm talking like tiny degrees, like 0.001 degree, maybe even smaller angles than that. But yeah, they bend

This varies between individuals and is related to age, state of health and diet. People whose bones are inflexible with little tensile strength suffer from 'brittle bone disorder'.
