Baby’s first cold!

M

When is the right time to call the pediatrician for an 8 month old with a cold? So far no fever he just has a really runny nose and watery eyes and bright pink cheeks. He woke up screaming every hour last night like he was in pain but again no fever. I kept nursing him a lot last night and I can tell he was really congested. Today he’s a little grumpier than normal but I’ve gotten a few smiles out of him. Anyway my question is when to call the pediatrician? Thanks!
