According to the Nemours Foundation, approximately 2%-3% of infants have a milk allergy and usually outgrow it. (citation) And according to Dr. Alan Greene, at least 30% of infants with cow's-milk allergy are also allergic to soy. (citation) When you consider that 4 million babies were born in 2003 in the United States alone (citation), this equals approximately 24,000 new babies each year with both milk and soy allergies or sensitivities.
When I was breastfeeding my new daughter, my husband and I (thanks to our pediatrician) discovered she had food sensitivity issues with milk and soy proteins. I had to either cut milk and soy products from my diet, or stop breastfeeding my baby and switch completely to hypo-allergenic formula.
Completely switching to formula was not an option for me, so I began eliminating milk and soy products from my diet - including butter, cream, cheese, and all soybean oils! I became exasperated, wondering "What can I eat?" and nearly bursting into tears in the middle of the grocery store trying to find a single loaf of bread that did not contain milk, casein, whey or soy, including soybean oil.
I was overwhelmed. I had to completely re-think eating and grocery shopping. I lost so much weight in two weeks, my milk production decreased. I was not getting enough calories.
Slowly, I learned which brands made products without soy or milk products. Slowly, I made a list of what I could eat as quick snacks. Slowly, I developed my own way of cooking that enabled me & my husband to get enough calories without causing allergic reactions in our baby.
I began to find online message boards with other nursing mom stories like mine. Lack of food options, frustrated grocery store trips.
I created the Nursing Mom Recipes web site for those moms. And now, I've started the Nursing Mom Recipes Blog, so that others can post their recipes and helpful hints for breastfeeding moms whose infants are allergic to soy and milk proteins.
