The "soft spot" is the area on top of the head where the bones of the skull have not quite joined. During pregnancy, the skull develops sort of like a jigsaw puzzle; it's not all one bone, but rather many bones that eventually meet and fuse. Some bones meet and fuse before the baby is born. Others fuse after birth to allow room for the brain's tremendous growth over the first year. More than 50 percent of the total growth of the head occurs in this first year of life. If all the bones fused early, there would be no room for the brain as it grows.
There are often several "soft spots" present at birth, but most are so small and last for so little time, that parents are unaware of them. But by two months, only two of these spots should be present:
The smaller is the posterior fontanel, on the back part of the top of the head. It's usually difficult to find at two months of age and should be completely gone (because the bones have fused) by four months.
The anterior fontanel is the one most parents recognize as the soft spot. It's on top of the head toward the front. Four bones come together at this spot, but, because of their rounded corners, they don't quite meet. This soft spot may close as early as nine months of age or as late as two years. The average is between 12 to 14 months.

The soft spot is where the skull has not completely closed up, this allows the brain to grow. In fact there are two soft spots, one on top and one on the back of the head. Without these the brain would not beable to grow and it would be damaged. It takes about a year for this to close all the way.

The "soft spot" is the area of the baby's skull that has not closed yet. In every baby, the bones of the skull are not completely closed to allow for brain growth. So, underneath that soft spot is the baby's brain, hence why it's so delicate. The proper term is the fontanell.

The soft spot is on the top (back) of a babies head. It is there because the parts of the skull haven't came together yet so the skull is weaker. Other wise giving birth would be way more painful. Hitting or injuring it could cause brain damage because your brain is protected by your skull.

The soft spot is where the sutures of the baby's skull have not closed. There are actually 2, one on top and one on the back of the head.

the soft spot is a small section on the babys head where the bones have not grown together. It helps the baby and mother when the baby is born because the head has room to be squished just a little so that it can actually move around the mothers bones.

The soft spot, or frontanels, are areas in the skull that have not been fullly enclosed by the bones yet. There purpose is to allow the baby to come through the birth canal with ease by slightly going together.

The soft spot is on top of the baby's head and its the part of their skull that has not closed yet. If you touch or hit it to hard it can really hurt the baby so just don't mess with it.

It is called the fontanel. This is the area of the skull that has yet to grow together. As the brain develops these areas of the skull close in together to form a protection for the brain.
This area is soft because it is only being protected by the thick layers of the brain (meninges, if I remember correctly) /membranes. If this area isn't protected, it could injure the brain.

It is the spot on the top of their head nearer the front where the skull has not completely fused yet. It does have some protection, but you still have to be semi careful. It is a baby, so you are usually pretty careful anyway.
