• Wheezing, or noisy breathing, is a high-pitched, whistling sound, which happens when the small airways become narrow, making it difficult for a baby to breathe.
• It is a common problem in babies, and in general, babies and children wheeze more often than adults because of differences in the size of their airways.
• It can be due to a chronic illness such as a respiratory tract illness, a cold virus or to food allergy. When it’s a food allergy it usually occurs with other symptoms, and these can be very different from one baby to the next.

Respiratory issues such as an ongoing cough is commonly caused by an infection. Therefore, an ongoing cough should only be considered if it exists in the absence of an infection (or in combination with other symptoms) and has persisted for 1 week or more.

Once completed, this chart should be reviewed by your baby's healthcare professional.
