10 month old with a cold

I’m a FTM and unfortunately I’ve had a cold for the past few days. I tried staying away from my son so he wouldn’t get it but when you’re a SAHM and the primary caregiver that becomes awfully hard. Tonight, while my baby has been sleeping.. I’ve noticed my son is starting to sound a little congested. He was getting fussy in his sleep (hence the reason I’m up right now) because he kept making a funny noise breathing with his pacifier in his mouth. Definitely the start of our first ever cold and I’m clueless. I plan on calling his pediatrician when they open in a few hours but does anyone have any tips or advice on what to do to make him feel better? We are going away next Thursday 11/29 and it couldn’t of come at a worse time. Thank you!
