L.D.
I've been through this many times with my own son (he's now 4). The most important thing right now is to count his respiraiton per minute, especially if he has been coughing a lot, if you are thinking you need to take him in. If he is breathing rapidly, it means he is having a hard time breathing. Rapid breathe also comes from high fevers but it doesn't sound lik ehe has a high fever. 99.2 is not a fever. I learned about counting breathes after calling my own ped in the middle of the night. Google 'Pediatric Respiratory Rates' or go by this: Infant up to 1 year 30-60 breaths per minute. Anything higher than 60 breathes per min. and take him in ASAP.
