Finding sources of fat and calcium is very difficult for moms breastfeeding MSPI kids. Many people (even lactation consultants and dietitians) suggested goats milk (and goat cheese and yogurt) as viable options. A chat with our allergist revealed that goat milk-based products are NOT safe for MSPI kids.
Bovine albumin (the protein that causes the irritation) and goat albumin have 97% structural homology. This means that the two proteins are almost identical and cause identical symptoms.
Enriched rice milk is a good source of calcium and can be used instead of milk in most recipes. I have yet to find alternatives for cheese and yogurt.
