Foods That Cause Gas in Babies That Are Nursing

While all babies produce a significant amount of gas, you may notice persistent symptoms of gassiness and fussiness in your baby. According to Kelly Bonyata, licensed lactation consultant and founder of the website KellyMom, a mother's diet generally has little effect on the digestive tract of her child. However, gassiness accompanied by signs of an allergic reaction, such as hives, vomiting, eczema and wheezing, may indicate an allergy to a food ingested by a breastfeeding mother.

Vitamins and Supplements

A breastfeeding mother who takes vitamins and supplements may notice gassiness in her child. This excess gas is often accompanied by a rash, diarrhea, vomiting and a runny nose. These are all signs of a child with sensitivity to vitamins and supplements.

Any Foods Other Than Breastmilk

According to Bonyata, if your baby ingests any foods outside of breastmilk, this will most likely cause gassiness. An occasional bottle of formula, medicines, and solid foods can disrupt the digestive system of a breastfeeding baby and cause increased gas production.

Common Allergens

The most common allergens among adults and children are eggs, wheat, soy, corn and peanuts. If a breastfeeding mother eats any of these foods and notices a reaction of her own, the food may also cause a reaction in her child. Gassiness can also occur as the result of a mother eating a new food or foods she dislikes.

Cow Products

Cow products account for a large amount of food allergies, as well. Most commonly, babies react to the proteins in dairy products, not lactose. Switching to a lactose-free product will not eliminate excessive gassiness in breastfed children. This also applies to soy, goat and sheep milks. To test your child for dairy sensitivity, eliminate all dairy from your diet for three weeks. If symptoms disappear, continue with a dairy-free diet. Reintroduce dairy between six and 18 months. If your child still shows symptoms of a dairy allergy, try again intermittently. Most dairy-sensitive children can handle cow products by the age of three.
