When does the fontanel close? Early or late closure?
⚡ Short answer: Back fontanel closes by 2-3 months; front fontanel mostly closes by 12-18 months; it's covered by strong tissue—normal touching and washing won't hurt it.

My baby's fontanel is still open and I'm scared to touch it. When does it close, is touching the fontanel harmful?

I totally understand your fear about touching that soft area. But the fontanel is actually covered by a strong membrane, so gentle touching, even washing it while shampooing, won't harm it.
The back fontanel (the small one) usually closes by 2-3 months. The front fontanel (the triangle-shaped area on top) closes for most babies between 12-18 months; some babies take until 24 months. It's completely individual and not a sign of a problem just because it's open.
Early or late closure is checked by a doctor. But just being open is considered normal. You can touch it confidently and even gently massage it while washing.
If you still feel worried, you can ask your doctor during a checkup: "Will you check the fontanel status?" That will put your mind at ease.
