My baby is 4 months old and he is getting a small red pimple on his face and head also, is this an allergy?

A. hello dear if it is on the head as well the nearest it is possible that it is allergy this can also be because of the extreme hot weather so it's better to give your baby bath every day keep it in the Well ventilated room making wear cotton clothes avoids sweat on his body as much as you can still is not any difference and definitely you need to consult the doctor
