Hi,
The most likely cause of this illness in an infant is due to a virus. The big concern is the state of her hydration. Does she have a fever? Or:
-
dry mouth and tongue
-no tears
-doughy feeling skin
-not wetting diapers with usual frequency?
Most significantly does she have her normal state of activity and alertness?
Since this is only her second day of illness, if she has no fever, does not show signs of
dehydration, and responds normally to you, then it sounds as if you can safely watch her at home for another couple of days.
Should she not have a fever (rectal is the best route) you may want to give her
Tylenol anyway for presumed body aches and possible
sore throat.
Assuming she has a sore throat, in addition to your milk, you may offer slightly chilled
Pedialyte and small pieces of Popsicle.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Arnold Zedd,
