What temperature is counted fever for infants? My baby is 2 months old. She is having a temperature of 37.8 What do i do?

If your baby shows lethargic symptom or inactive unlike usual, it is best to bring her to doc immediately. Otherwise,if she is happy and eat and drink well, just keep her body and environment cool, especially during this hot season. Wear cotton clothes, let the air in the room cool and make sure she drinks milk/breastfeed whenever necessary.
