As a parent you always want the best for your baby and that includes protecting them from anything unpleasant or harmful. When repeated tummy troubles or other symptoms strike after feedings, you might be asking yourself: "Does my baby have a milk allergy?" It's a reasonable concern and there are things you can do to keep your baby safe.

Jan Kajzer, MS, RD, LD, an Abbott pediatric nutrition researcher specializing in food allergies, shares what to look for. 

Spotting the Symptoms

Cow's milk allergy symptoms can be as mild as a rash or a runny nose or they can be extremely dangerous. When you're caring for an infant who can't speak, trying to figure out if your child is allergic to milk can be tricky. Knowing these common food allergy symptoms can help:

Another clue is timing. Symptoms usually start to appear a few minutes to two hours after eating, so pay close attention in the time directly after your baby eats to see if an allergy could be the problem.

Your Healthcare Provider Can Help

Cow's milk allergy is most likely to develop during a baby's first year. Because the incidence of food allergies is on the rise they're on many parents' radars. However, they can also be misdiagnosed by well-meaning parents trying to soothe an uncomfortable infant. That's why it's especially important to speak to your baby's doctor if you suspect a food allergy. They'll be able to do a full exam, take a history of all symptoms and even refer you to an allergist.

Feeding Your Baby

Even small amounts of milk can cause a reaction in a milk-allergic baby, and since there's no cure for food allergies, parents need to make sure that their baby strictly avoids all milk and milk-containing foods.

If you're breastfeeding, you may be advised to avoid these items as well since the proteins can be passed through breast milk. For formula-fed babies, a doctor will likely suggest a hypoallergenic formula where the protein has been extensively hydrolyzed or broken down such as Similac® Alimentum® . If the baby cannot tolerate the extensively hydrolyzed formula, you may be advised to use an amino acid-based formula, like EleCare. After baby's first birthday, your doctor will recommend the best milk-free alternative beverage for your baby.

Milk allergies aren't just about what's in your baby's bottle. If your child has started eating solid food, you'll also need to make sure that they avoid all milk-containing foods such as yogurt or cheese. Because milk can be in many foods, your baby's doctor may also refer you to a registered dietitian to help you learn to look for problem ingredients.

Communicating With Caregivers

If you're like many parents, you may not be the only person who feeds your baby, and educating anyone who cares for them is critical. If a grandparent or babysitter is routinely responsible for your child, it can be helpful to invite them to join you when you visit the doctor or dietitian. For kids who go to daycare, you may want to schedule a time to sit down with the center's administrator to discuss your child's diagnosis as well as milk avoidance strategies. Many daycare centers have experience dealing with food allergies and have policies in place to ensure that your baby is protected from any exposure to milk.

Managing a milk allergy can be daunting but with the right support and resources you can protect your baby and ensure they get the needed nutrients to grow strong and healthy.

One of the most exciting parts of caring for your baby is watching them grow and reach new milestones right before your eyes. They'll develop an appetite for and interest in solid foods during their first year of life. Your job, during this exciting journey together, is not only to guide their nutrition but also to decode their unique language of cues — a symphony of expressions, gestures and coos in reaction to these new sensations.

Breast milk is considered the gold standard, but some parents can’t or choose not to breastfeed, while others rely on both formula and breastfeeding. Those who use formula should know how to make a baby bottle to keep their baby healthy. It's simple, but important to carefully follow the label instructions. Questions about feeding your child should be directed to a healthcare professional.
