Hi, Have a 16 month old with a cold... saw dr 11 days ago and baby had just developed a rash on stomach/chest and had beginning of ear infection...dr said rash was due to virus. We just finished antibiotics and baby still has cold but what concerns me is now rash has spread to back, neck, legs, feet, hands...the rash does not seem to bother him. his cheeks are red, almost rash like but i think that is due to runny nose. when will this rash go away or should i call dr? he hasn t had any fevers.
