Symptoms and feeding patterns in the first year of life.
With the help of family doctors, mothers and infant welfare sisters, we report an analysis of symptom and food diaries maintained throughout the first twelve months of life on 482 infants. This reveals the existence of extensive symptomatology in the first year of life--most of which was clearly unrelated to ingestion of foods or cow's milk. Our efforts to define the true incidence of cow's milk allergy have been unsuccessful. Altogether, 77 of the 482 diaries have revealed symptomatology at some time in the year which could conceivably have been associated with cow's milk ingestion. But, in only one of these 77 children were withdrawal and challenge tests carried out to determine whether the symptomatology disappeared on withdrawal of cow's milk and reappeared on its reintroduction into the diet. Most of the remaining 76 children had long periods of complete freedom from symptoms whilst taking cow's milk, and the evidence of any association with cow's milk was generally very tenuous. Soya substitutes were introduced in 13 cases, and cow's milk was temporarily discontinued in another 11 cases. Only 16 of these 77 children continued to experience chronic symptoms during the last two weeks of their first year.
