Tylenol for cold?

My son is 8 months and has never been sick until now. Sneezy, a little congested, runny nose, puffy eyes every now and then. I’ve been using our nose frida, face wipes to wipe his little snotty nose lol, and we’ve been giving Tylenol 3-4 times a day. This is our third day of this. Is this okay? Should we be doing anything else? He has his 9 month check up in a few days. Thanks mamas!
