The causes of sweating in children when they are breastfeeding include the following: first, normal physiological reactions. This is because children will sweat when they are breastfeeding, and they will also suck hard on the nipple, etc. Sweating is a normal physiological reaction and requires no special treatment. Secondly, it is caused by the child’s deficient qi constitution. If a child has a deficient qi constitution, it is easy to sweat, especially if the child eats milk and uses all the strength, the sweating will be more obvious.
