Hello girls, 2 days as temperature 37-38.5. No throat or nose is bothering, it hurts, it burns the left breast, there are no lumps, what could this be? With milk everything is in order, it doesn't taste bitter, the color doesn't change. Can I feed the baby with a fever and what to drink to bring down the temperature? Help please.
