Yes， it is normal for an 11-month-old baby to sweat， as sweating is one of the ways the body regulates its temperature.
As babies are not able to regulate their body temperatures as well as adults， they are more prone to sweating. This is especially true in hot and humid weather or when they are dressed in too many layers. It is important to keep your baby cool and comfortable in such situations by dressing them in breathable clothing and keeping them in a well-ventilated space.
Excessive sweating， however， can be a cause for concern， as it may be a symptom of an underlying medical condition. If you notice that your baby is sweating excessively or more than usual， it is advisable to consult a pediatrician. Other symptoms to look out for include fever， irritability， lack of appetite， and general weakness.
Some medical conditions that can cause excessive sweating in babies include hyperhidrosis， anhidrosis， and congenital heart disease. Hyperhidrosis is a condition where the body produces sweat in excess of what is needed to regulate temperature， while anhidrosis is a condition where the body does not sweat enough to regulate temperature. Congenital heart disease， on the other hand， can cause sweating as a result of the body working harder to pump blood due to a defect in the heart.
In conclusion， sweating is a natural bodily function and is normal for an 11-month-old baby. However， excessive sweating can be a cause for concern and should be brought to the attention of a pediatrician. As a parent， it is important to ensure that your baby is comfortable and well-ventilated， especially during hot and humid weather.
