Advice for Bronchitis?

Tucker’s developed bronchitis.  He received two steroid shots yesterday which helped with his cough.  As we had to go to an office with Saturday hours, he didn’t see the doctor that he usually does and she suggested antibiotics, which I refused.  From what I understand, bronchitis is usually viral, and antibiotics don’t help.  Tucker’s never had them, and I don’t want to give them to him unless they’ll help.  Google has informed me that bacterial bronchitis (which is helped by antibiotics) is usually accompanied by a productive cough, which Tucker’s is not.

Last night, he slept a bit here and there, always in a sitting position.  He took off his pajamas and was sleeping naked against the wall, so we transferred him to our bed, where he caught a few more hours sitting up against me.  I don’t know what he’s feeling (he can’t articulate sick thoughts) and I’m not sure what to do.  He’s also grabbing his penis a lot – is this a sign of dehydration?  Because he’s ingesting very few fluids.

Any advice?  I’m waiting on a call back from the doctor’s office but moms usually know what to do…so I’m asking you.  Thanks!
