Please tell me again, is 37.3-37.5 degrees Celsius normal for a two-month-old baby? Should I lower it? And generally, what's the normal temperature until one year old? I see online that up to one year old, 37.4 degrees Celsius is considered normal. But the pediatrician says this isn't normal for our age.
