My 19 month old daughter seems to always have something. 3 weeks ago she had a chest infection and got given antibiotics. She has now stopped coughing and no longer has a runny nose, but, just after about a week of being back to normal, she now has a fever (with no other symptoms). What is going on? She has had cold after cold after fever after cough... for absolutely ages. How normal is this? She goes to nursery 3 days a week and has an older sister, so I would expect her to be sick often, but how often is too often? What is normal at this age? Any information or similar experiences would be welcome.
