Detailed explanation-1: -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.
Detailed explanation-2: -In an infant, the space where 2 sutures join forms a membrane-covered “soft spot” called a fontanelle (fontanel). The fontanelles allow for growth of the brain and skull during an infant’s first year. There are normally several fontanelles on a newborn’s skull.
Detailed explanation-3: -Typically, fontanelles close by the time your baby is 18 months old. The posterior fontanelle usually closes first-within 2 months of birth. The anterior fontanelle closes between 7 and 18 months. If you feel your baby’s fontanelles are closing too soon or haven’t closed in 18 months, consult your pediatrician.
Detailed explanation-4: -Fontanel (fontanelle): The word fontanel comes from the French fontaine for fountain. The medical term fontanel is a “soft spot” of the skull. The “soft spot” is soft precisely because the cartilage there has not yet hardened into bone between the skull bones.
