My son is 4m old, he has been very fussy, screaming at times.

He's been sleeping through the night and now he's very fussy.

His nose is runny and sounds stuffed and has a little cough. I can tell he is not the happy little baby I usually have.

He whines.

I've been suctioning his nose out and gave him 1.5mg of infant tylenol. A long with sitting with him in bathroom with steam.

If not better by Monday I'll call his PED.

Any advice. ???
