Umbilical hernias are common in newborns and infants younger than 6 months. They occur when part of the intestines bulge through the abdominal wall next to the belly button. In babies with umbilical hernias, parents may see bulging around the belly button area when the baby cries. Unlike other types of hernias, umbilical hernias may heal on their own, usually by the time a baby is 1 year old. If not, surgery can repair the hernia.

Soil Taxonomy is based on the properties of soils as they are found in the landscape. One objective of the system is to group soils similar in genesis, but the specific criteria used to place soils in these groups are those of soil properties. Because Soil Taxonomy is a hierarchical system each soil is grouped first in the broadest category first. When more details are added lower categories are defined.
