Doctors are advising parents to feed babies peanut products before their first birthday to reduce the child’s risk of developing a peanut allergy. The advice appears in a new guide for health care providers. It was published in the Canadian Medical Association Journal. A team of allergy experts and child care specialists wrote the new guidance. They suggest adding soft, crushed peanuts to a baby’s diet beginning at four months of age. They say babies should continue to get “substantial” amounts of peanut products in their first year of life. Doctor George du Toit is with King’s College London in Britain. He helped prepare the guide. He said it is important to speak with a doctor early on to make sure the child does not already have an allergic reaction.
