It is completely normal for babies to have a soft spot, also known as the fontanelle, on their heads. The fontanelles are areas where the skull bones haven't fully fused together yet, allowing for flexibility during childbirth and brain growth in infancy. The soft spot at the back of your baby's head is called the posterior fontanelle.
The presence of a soft spot is not something to worry about; it is actually an essential part of your baby's development. However, it is important to handle it with care as it can be sensitive.
The posterior fontanelle typically closes between 6 and 8 weeks after birth, but every baby develops at their own pace. It may take up to several months for it to completely close. During this time, you may notice changes in its size and shape as your baby grows.
While most cases are harmless, there are certain situations when you should consult your pediatrician:
These could potentially indicate underlying issues such as dehydration, infection, or increased pressure within the skull.
In general, if your baby is otherwise healthy and meeting developmental milestones, there is no need for concern regarding the soft spot on their head. Regular check-ups with your pediatrician will ensure that any potential problems are identified and addressed promptly.
