I was told by my GP that my dairy intake wouldn’t affect my baby Emily’s cows milk allergy. However, the Allergy Unit at Royal Prince Alfred Hospital disagree.
Proteins from the maternal diet are found in breast milk within a few hours and may be found for the next 24 hours or so. (Milk Allergy Information Sheet)
After reading their article and recommendation to stop dairy products, I found that Emily’s reflux symptoms and eczema went away. If I did slip up and have dairy, within an hour of her next feed the eczema and unsettled tummy would return and might last 24-48 hours.
