Cranial sutures. These bones are held together by strong, fibrous, elastic tissues called sutures. The spaces between the bones that remain open in babies and young children are called fontanelles. Sometimes, they are called soft spots. These spaces are a part of normal development. The cranial bones remain separate for about 12 to 18 months.
