Lactose intolerance is the result of a deficiency in the lactase enzyme necessary to help break down and digest lactose, a sugar most commonly found in dairy products. Although not a common condition for infants, lactose intolerance may result in increased fussiness, diarrhea and gas. Choosing the right formula for your baby is always important, but for those infants with lactose intolerance it can make the difference between a cranky or comfortable child. Your child's pediatrician can help you determine which formula is best for your infant.
Lactose-Free and Low-Lactose Formulas
Unlike with a milk allergy, many children can tolerate small amounts of lactose in the diet and can continue to consume a formula that contains milk products. These formulas may have cow's milk proteins in them. They are often easy to digest for babies with lactose sensitivities. Similac Sensitive is formulated to help prevent malabsorption issues and Enfagrow Gentlease has only about 50 percent of the lactose of standard formulas, and has partially digested proteins. Nestle's Good Start Gentle formula is also designed for easier digestion. All are milk-based products.
Soy-Based Formulas
Soy-based formulas are generally milk and lactose-free for babies that have difficulty digesting milk products. Enfamil ProSobee, Nestle Gerber Soy and Similac Soy Isomil are common soy-based formulas available.
Elemental Formulas
Elemental formulas are designed for infants with lactose intolerance and more severe conditions such as protein maldigestion, severe food allergies and fat malabsorption. These formulas should be reserved for infants with a combination of problems and not necessarily for lactose-intolerance alone. Similac Expert Care, Nutramigen and Pregestimil Lipil are available elemental-based formulas.
Re-Introducing Standard Formulas
Many companies provide transitional formulas for babies older than 9 months. Several varieties are available and special dietary needs can be accommodated. Because lactose intolerance is not an allergy, re-introducing lactose products when approved by a pediatrician can minimize future side effects associated with the condition. Trials of small amounts of lactose and increasing the dosage over time may help eliminate the severity of the lactose intolerance.
