hello. It is a real-time problem solver.
[소아청소년과]You have concerns about this. We will answer your questions.
I understand your concern about the condition of your baby’s fontanel.
The fontanel is a soft area located in the center of the top of the baby’s head, a space in the skull that is not completely closed. This area closes completely between 12 and 18 months of age.
The most common cause of a sunken fontanelle is lack of moisture. The questioner said that he noticed that it came back up when he gave him water, so it is likely that this was a symptom of dehydration. Other causes may include:
- decreased feeding volume
- When you have a fever
- Temporary changes during growth
- Digestive problems or changes in bowel patterns
Your baby’s frequent pooping may be related to their digestive system, which can affect their water balance.
In general, it may be normal for the fontanel to temporarily turn off and then come back up after hydration. However, you may want to consider a hospital visit in the following cases:
- If the fontanel is consistently off and does not recover even after hydration.
- If your baby is fussier than usual or seems lethargic
- If you have a fever or are accompanied by other abnormal symptoms
- When the amount of feeding is significantly reduced
Please continue to monitor your baby’s condition, maintain adequate fluid intake, and if symptoms persist or you are concerned, it may be reassuring to consult a pediatrician.
