Have any moms out there had children that had the cold and were getting better but then woke up with a cough and runny nose; then woke up from a nap hours later with gunk coming out of their eyes that lasted so far, two days? My son is going through that right now and I'm wondering if I should just keep doing a hot compress or if I should just take him to urgent care? Any advice?
