Runny Noses and Itchy Eyes
For the first day or two of a cold, noses may run clear, but the mucous soon takes on a yellowish or greenish hue. If your child has had a runny nose for a week or more and the mucous remains clear, it is a strong sign of an allergic reaction.
Do you catch your child persistently itching their eyes, even grinding little fists into reddened sockets? Colds and fevers can make eyes red or runny, but itchy eyes usually means allergies.
