It is not surprising that some parents wonder if lactose intolerance in babies causes colic, or persistent crying. After all, lactose intolerance in adults is quite common...why wouldn't it aggravate infants?
Think about it: If it did, there would be no ‘witching hour.’ Lactose consumption is pretty steady throughout the day, but colicky fussing tends to peak in the evening. But allow me to explain how this theory got started, and why it is a myth.
The lactose your baby eats is digested by the enzyme lactase in the intestine. With age, adults have less and less lactase. This makes some of us lactose intolerant causing bloating, bellyache and diarrhea after eating dairy products. This adult problem led some medical professionals to speculate that colicky babies might be suffering from stomach pain from lactose intolerance.

But this multimillion-dollar promotion was based on hype not health. A Canadian study showed no improvement from lactose-free formula in colicky babies. And an Australian study found no reduction in crying when fussy infants were given lactase in their mother’s milk.

Es importante que, en preparación para la lactancia y durante la misma, las madres lleven una dieta saludable y equilibrada. La combinación de lactancia materna y alimentación con biberón en las primeras semanas de vida puede reducir la producción de leche materna y es difícil revertir la decisión de no amamantar. Si decide utilizar fórmula infantil, debe seguir las instrucciones cuidadosamente.
