If the child is in daycare with other children, he is going to have LOTS of colds and fevers. Colds are no big deal. Treat the symptoms, the cough, the nasal congestion with over the counter meds OR no meds at all.
(That was my mother's saying:
Cure a cold with medicine in six days, or without in seven.
The problem is, by being around the other children~all of whom have colds occassionly too~, he will constantly pick up some other kid's virus. Remember Antibiotics do NOTHING against viruses linked to colds.
Just treat the colds as they come. Plenty of liquids, tasty fruits,,,WASH the kid's hands and face every chance you get and, if he's really miserable (like doesn't want to play) a dose of acetaminophen to reduce his fever.
Fevers are something else. but what is
his temperature? 100°-104°F temps are nothing for a child. Plenty of fluids, bed rest and a change of clothes every few hours.
Temps over 104°F should be brought to the immediate attention of an MD and an alcohol bath administered.
(If you don't know how to do the bath, learn. )
Every kid gets colds. The kids who get a lot of them and are cared for without antibiotics will develop resistances against many of the common cold viruses.
My kid, an attendee at MANY daycares, reports he never gets a cold.
