The fontanelle generally closes 3 months after birth, while the fontanelle closes at the age of 1 to 1.5 years. Baby’s fontanelle is actually far less fragile than one might think. If one accidentally touches or presses the fontanelle, there is generally no great impact on the child, as long as one does not deliberately touch it. In winter, it is okay to wear a thicker hat when you go out. Even if the fontanel area is touched, it does not affect the child particularly badly. If the child is not screaming, crying, drowsy, or vomiting, there is generally no need for special treatment.
