Hello K.,
Here's some advice from my experiences... I have nursed all three of my children, my son (3) had reflux so he would spit up alot. I beat myself up over what I ate, drank, etc... I have read that foods and drinks peak about 45 minutes after consumption in breastmilk. My youngest (6 mos.) was having issues too, the first thing that was recommended was eliminating dairy from my diet (she was strictly breastfed too), I was hesitant but willing to try, sure enough, all is well again. Two things that helped were my meeting with a dietician; referred by the pediatric GI Doctor, she gave me ideas and recipes, etc.. to make the transition easier, and I am now taking Calcium supplements and "living" a dairy free life. My family still eats/drinks dairy, and I used to eat cheese, chocolate, etc.. like it was going out of style! As a result I have lost 14 lbs. over the past month, unintentionally, but what an eye opener!
We were told that dairy allergies are very common and usually the first cause of colicky, uncomfortable, breast-fed babies. It was hard, you don't realize how many everyday foods contain dairy products. Talk to your pediatrician, see what they recommend for you and your little one.
Good Luck, feel free to contact me for further advice...
Take Care, J.
