How is little red dot suddenly on the baby's face?

Red spots suddenly appeared on the baby's face, which may be eczema caused by hot weather or humid environment.

Because the child is relatively young now, it is recommended to go to the hospital for dermatological examination in time to determine the cause and actively use drugs. If it is prickly heat, the indoor temperature should not be too high at ordinary times, but be careful not to let the child catch cold. It should be fine soon. You can also apply milk to your baby first, and go to the hospital in time if the effect is not good. Thank you.
