6months
This one closes fairly early, usually by the time the baby is 2 months.
Babies have six, four of them are closed during the intrauterine life. Posterior fontanelle is closed when baby is born, but it can be closed 2-3 rd month. Anterior fontanelle which is closed last, must be closed at 18th month lasltly.
Firstly, most people are unaware that babies actually have a baby soft spot on the top of the head which is diamond or kite shaped (anterior fontanel) and another one at the back of the head which is triangular (posterior fontanel).A newborn's soft spot exists where the skull has not completely closed at birth. The anterior fontanel is generally about two inches wide and can remain to some degree until the baby is around eighteen months of age. The posterior fontanel is only half an inch wide and closes relatively quickly between the ages of six to twelve weeks.Essentially, the soft spots are an area of an infant's head where the skull plates have not yet formed together to protect the brain.the soft spot in the babies head where the skull is not fully developed.
The anterior fontanel
You could on a baby whose fontanel (I cant spell) hasn't closed yet. However, I would strongly discourage trying this at home.
The fontanel or fontanelle is the soft spot on a baby's head.

The anterior fontanelle was soft at birth as this allows the baby's head to exit the birth canal safely. As the baby gets older, the fontanelle closes and hardens to a normal skull.

This could be normal (especially if the baby was a pre-term baby). however, points you need to know are: - Usually the anterior fontanelle closes anytime between 8 to 18 months. - Delay beyond the second year, may be an indication of a bone disroder (like rickets) or due to increased intracranial pressure (mass-occupying lesion or simply hydrocephalus)
