When you call, I'll ask you what the baby's temperature is, how it was taken, and some other things like changes in feeding or activity level. I may need to see the baby to find out what's going on. Anticipate colds Many babies have their first cold before they are three months old. Cold are caused by viruses, not cold air or drafts.
