This is a good question.The answer usually depends on the child's environment and circumstances. Young children who attend a creche come into contact with other children with coughs and colds and are often ill especially during the winter months. Some children are more likely to get chest infections especially those who are a bit overweight and those children who are exposed to cigarette smoke at home.There are many children who get what is known as recurrent vitral wheezing due to repeated chest infections with viruses. You are correct it does appear that these children have narrower airways than others of their age. This illness usually disappears by the age of 3 or 4 years. Do not use a nebuliser with saline regularly as it may aggravate your child's cough and wheeze.
