My baby sweats a lot, much more than normal. What must be reason? What should I do?

To be certain that your baby is not sweating due to discomfort, dress your baby in cotton clothes if the weather is hot and humid. You can also give your baby some naturally cooling drinks, such as lassi, tender coconut water, lime water and such to regulate the body temperature and reduce sweating. Sometimes, excessive sweating can be caused due to a condition known as hyperhidrosis, where the sweat glands are more active than usual. If the sweating is excessive, it could also point towards illnesses related to the heart. Do not be alarmed, as your baby's doctor will be able to provide the right consultation and treatment options. I came across an article that talks about the condition in young kids, see if it helps http://www.aboutkidshealth.ca/En/HealthAZ/ConditionsandDiseases/Dermatology/Pages/Hyperhidrosis.aspx
