2 yr toddler constantly sick. fever 3 times a month, cough, runny nose when no fever. goes to child care. gps say 'normal'. is it? toddler seems happy even when sick.

Most likely normal: If your child is otherwise well, the immune system is developing, and frequent infections may occur at this age. If there are specific recurrent infections, unusual infections, multiple courses of antibiotics, an immune work up may be indicated. Rinse the nasal passages with saline, ensure a clean environment, and avoid ill contacts. A flu vaccination is recommended.
