Sick Baby, Worried Mama

Laura

My baby girl has been sick for the past 3 days. She started running a fever yesterday which I brought down by altenating between Tylenol and Motrin. Last night, however was tiresome. Her fever returned twice and we didn't sleep well either. She has a nasty cough, congested, and runny nose. She is also clingy (not usual behavior). Her cousin's were diagnosed with pneumonia and she was around them while they were sick. I took today off to keep an eye on her. Debating on going to the ER to ease my mind. She hasn't been this sick since she contracted RSV when she was 2 months old. I usually don't go running to the doctor when she gets a sniffle, but something is telling me go and get her checked out. What should I do? Go or wait it out?
