Doctor's answer:

Sweating during sleep is a normal phenomenon for babies, as children have more developed sweat glands. After falling asleep, the vagus nerve becomes excited, leading to increased sweating. This is usually more noticeable on the head and face but typically subsides within one to two hours. If the baby continues to sweat after falling asleep and the amount is significant, it could be a sign of a functional disorder of the vegetative nervous system, with some cases possibly being caused by calcium deficiency. It is recommended to actively implement calcium supplementation treatment. Wishing the baby healthy growth.
