9 month old with another cold

Ang

hi all! so my LO caught another cold right before new years. first it was just a bad mucusy cough and now he has a stuffed runny nose. I've been alternating between Tylenol and Advil and giving him zarabees (without honey the one for babies 2 months and up). I use saline spray and nose Frida too. what worries me is that he won't drink his formula! today he barely drank more than 8 oz. he has pooped and peed bit not as much as usual. and he's been crying all day. he's currently napping on my shoulder as I type this. I'm going to call the Dr in the morning ( we are currently out of town visiting my parents leaving to go home tomorrow).

any advice would be appreciated!
