When will the soft spots on my baby’s head close? What do I need to do to protect them?

Baby’s soft spot is actually two spots called fontanels — one toward the front of that sweet little head; another smaller one toward the back — and they’re gaps between the bones of baby’s skull. The back fontanel will close first — typically when a baby is between 2 to 4 months old. The front one, however, stays open well into baby’s 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. The soft spots actually are well protected by a sturdy membrane. It's okay to touch them (gently of course). http://www.whattoexpect.com/first-year/ask-heidi/baby-soft-spot.aspx
