Sweat rash (miliaria)

A heat rash, sometimes calledmiliaria or prickly heat ,may flare upwhen your baby sweatsfor example, because they're dressed in too many clothes or the environment is hot and humid.

It's a sign your baby's sweat glands have become blocked. They may develop tiny red bumps or blisters on their skin, but these will soon clear without treatment.
