Doctors advise mothers to breastfeed their baby for as long as possible, and if breastfeeding proves difficult, they should stop for a while and try again. Parents with a family history of allergy are advised to give their children hypoallergenic infant formula (with added lactase enzyme to cut down protein particles, because milk proteins can cause allergies). In this way, asthma and allergies can be reduced by a third in children.
醫生建議儘量餵食母奶，如果有困難，退而求其次，有家族病史的小朋友，則建議採用低過敏奶粉（加入酵素將蛋白質切小，因為大分子的蛋白質較容易引起過敏），如此一來，兒童發生氣喘、過敏的機率可以降到三分之一。
