Cow's milk formula as a cause of infantile colic: a double-blind study.
The role of cow 's milk in infantile colic in formula-fed infants was estimated in a double-blind study . Sixty colicky infants were given a cow 's milk-containing formula ( Enfamil ) and a cow 's milk-free formula based on soy ( ProSobee ) . Eleven infants ( 18 % ) were free of symptoms while receiving soy formula .  Symptoms of 32 infants ( 53 % ) were unchanged or worse when they were fed cow 's milk formula and soy formula , but symptoms disappeared when they were fed a formula containing hydrolyzed casein ( Nutramigen ) . Symptoms of 17 infants ( 29 % ) could not be related to the diet ; these infants were permitted to continue on a cow 's milk-based formula . A challenge with cow 's milk-based formula after one month ( at approximately age 3 months ) produced symptoms of infantile colic in 22 infants ( 36 % ) . At age 6 months , a challenge with cow 's milk was positive in 11 infants ( 18 % ) with epidermal and gastrointestinal symptoms . Eight infants ( 13 % ) at 12 months of age and five infants ( 8 % ) at 16 months of age were still intolerant to cow 's milk . Cow 's milk seems to be a major cause of infantile colic  in formula-fed infants . A dietary treatment is suggested for moderate or severe forms of the colic . Cow 's milk protein intolerance is common later in infancy in these infants
