ventolin can help your baby to breath better by relaxing the muscles in your baby's airway and dilating the airway, however, your baby's airway can only stretch so much therefore if you use ventolin more than 5times a week you will need an orange preventer inhaler which also improves baby's breathing but by clearing the mucus in the airway. Hope that helps, sorry I'm at work so can't type Chinese作者: 小丸子1979 时间: 2010-7-12 22:38:20
