I would suggest giving your doctors office a call and talking to a nurse. Usually, they have a triage nurse that will discuss the symptoms with you and tell you if it is something to be concerned with, what to watch out for, and if you should bring her into the office to get checked out.
It doesn't sound like anything worrisome. At that age, my son slept a lot anyway, but they tend to sleep even more when they are sick. As Jackie said, she may not be sleeping well at night because of the congestion, and so she may be trying to catch up during the day. Hope she feels better soon. |
