What bronchiolitis symptoms do babies and toddlers have?

Wheeze, cough: Bronchiolitis usually caused by RSV generally causes wheezing and coughing along with difficult breathing. Symptoms can vary from mild to severe requiring hospitalization at times.

Wheezing!: Babies with bronchiolitis, or a viral infection of the small airways in the lungs, have cough, funny nose, fever and wheezing. They may have decreased appetite and have trouble sleeping. If your baby is breathing fast, wheezing, or has a persistent cough, see your pediatrician.

Nasal mucous, cough: Babies and toddlers with RSV virus infection have lots of nasal mucous, so they have some trouble breathing through the nose. The mucous also forms in the lungs, so they cough and wheeze. They breathe fast, making it hard for them to eat or swallow. They work harder to breathe, sometimes sucking in the skin between ribs, and get very tired. Hospitalization may be needed for symptoms like these.

Common cold: Early symptoms include runny nose, stuffiness, mild cough and sneezing. A few days later, more serious symptoms develop such as fever, trouble breathing, wheezing, irritability and flaring of the nostrils.

Crackles - fine: A symptom not mentioned above, but quite commonly seen with bronchiolitis is fine crackles on auscultation of the chest.
