Eventually, the bones in your babyâs skull will build up enough minerals to completely fuse together and those gaps will close. Youâll probably notice that the back fontanel will close first â typically when a baby is between 2 to 4 months old. The front one, however, stays open well into your babyâs second year (to give that amazing brain the space it needs to grow), though by the time your little one turns 19 months old even that fontanel should be closed. Normally, a babyâs soft spot is firm and curves in just slightly.
