DS has his first cold, and not sure if I should send him to daycare tomorrow. He is coughing, has a runny nose, and is swallowing lots of phlegm. Besides these things he is in a generally good mood and is eating and sleeping fine. I know he got it at daycare (first week there... lovely) because I saw another baby who had symptoms the other day. Should I bring him to the dr to get him "cleared" first? I don't want him to go and infect the other babies! DS is 15 weeks old.
