Parents or caregivers can try to minimize the amount of asthma attacks their child has by taking simple steps. These steps can include: keeping pets out of the bedroom, not smoking inside the house, using a humidifier. Parents should also make sure their children get enough sleep and exercise and that they are eating properly. Although it is known that there is no cure for asthma, there are treatments available for symptoms as well as preventative measures to keep children healthy and active.
