A 4 week-old infant and his mother came to my office last week. The mother had started seeing small flecks of blood and stringy mucous in the infant’s diapers a week prior. The baby was fine in every other way, breast feeding normally, and looked quite healthy when I examined him.
I diagnosed the infant as having cow’s milk protein-induced proctocolitis, the term referring to allergic inflammation of the lower gastrointestinal tract from exposure to cow’s milk.
This is a diagnosis I make often. Here's what you should know about infants with milk allergies:
- It’s more common than you think. 2-3% of infants in the U.S. are allergic to cow’s milk protein. It is even more common in infants with eczema or who have parents or siblings with allergies.
- It’s seen in breast fed babies. Over 50% of infants with this condition are breast milk-fed infants.
