Hello. My daughter is 18 months old and is suffering from diarrhea, runny nose, watering eyes accompanied with redness around her eyes. This is something she's goes through frequently. Symptoms just started tonight, and based on past experience, she'll have a cough in the next few days as well. We've noticed also that she seems to develop this sickness when we use our baby sitter. During the periods I was out of work, she seemed fine and never got sick. We're concerned she may be exposed to a toxin there we're unaware of? Or is she just exhibiting signs of allergies?
