There are several reasons why a 6-month-old baby is prone to sweating: firstly, a child’s basal metabolic rate is relatively high compared to adults, so don’t dress your child too thickly, if you dress too thickly your child is prone to sweating. Secondly, if the child has a history of repeated infections and is weak, excessive sweating can also occur. Thirdly, 6 months old babies grow and develop rapidly, and if there is a calcium deficiency, there can be excessive sweating, especially at night after sleep, which is not related to the surrounding temperature. The sweating can stimulate the baby to shake his head and thus cause occipital baldness, so if the child has excessive sweating, it should be analyzed on a case-by-case basis and given symptomatic treatment after the cause is clear.
