Baby's first cold :( What to do?

TeaForMe

My 12 weeker seems to have picked up the cold I had this weekend. He doesn't have a fever (as of now) but has a snuffly nose and has been just kind of out of sorts the last couple days.

 Since he doesn't have a fever and he's almost 3 months, do I need to still call the doctor and/or take him in? Or should I just see if things resolve on their own in a day or two? Anything else I could/should be doing for him to make him feel better? Thanks!
