It can be caused by laying your baby down with a bottle at night or poor diet (too many sweets, for example). Poor dental hygiene such as not brushing their teeth daily can also cause problems. Seek professional advice from a dentist.
If you have Rickets you can develop holes in your bones like I did when I was a kid.
Yes many of your bones have holes to allow blood vessel & nerve intervention as well as the interior of many of your bones are very spongy and therefore have holes that do not actually penetrate the surface of the bone, and are like little air pockets (only without the air) Many of the holes that allow veins and such to transverse them are termed "foramen" For instance your spinal cord enters your skull through a large hole at the base of the occipital bone. This hole is called the mental foramen. Plenty of tiny holes are found all over your bones and then there are obvious ones like the eye sockets (which allow the optic nerve(s) to pass to the brain) These holes make up the orbitals.
Because they have wings and Holes in their bones to make then lighter
Since vitamin D is necessary for bone development and growth, some sort of problems will occur in the bones. In children is causes something called rickets and in adults it will cause thin and/or weak bones. These are called osteopenia (little bone) and osteoporosis (bone with holes).
The type of muscles that wrap around bones are typically skeletal muscles, but muscles do not make the bones light. What makes bones light are the fact that they are porous. There are a lot of holes within the bones that make it lighter, but those holes make sort of arcs and what not, similar to those in the Eiffel tower, for example. They are light weight, but very strong.

Pollution causes global warming. It then causes ozone depletion.

Obstructions, black holes, etc.
The disease that causes bones to become weak is called "Osteoporosis".
The small holes in the bone surface are called osteocytes and they are responsible for nutrient and waste exchange. They help in maintaining bone health by communicating with neighboring cells and facilitating repair and remodeling processes within the bone tissue.
