sick 4week old😭

Veronica
My 4 year old daughter just started school and came home sick last week we tried to keep her away from our now 4week old son but now his is sick. he doesn't have a fever just really congested. I have a Vicks humidifier going and I but baby rub on his chest an he has had infant Tylenol(which his doctor said was okay) just wondering if any moms have any other ideas to help me?Â
