Mosquito cut on my baby's legs and red red spots on her leg and after dark spot on her leg please suggest me

A. hi dear Folliculitis happens when your baby's hair follicles become infected. If your baby has it, you'll notice little red or pus-filled spots around some of their hair follicles. These spots can appear anywhere on your baby's body that grows hair, most likely on their arms, legs, armpits or bottom.
