Cows Milk Protein Allergy

Mi

My newborn has the cows milk protein allergy and I need to eliminate milk products from my diet now. If you are someone who had to change your diet due to this issue, what are some type of quick food you ate for breakfast lunch and dinner ? I feel like I need to go vegan except I can still eat meat. It’s so hard eliminating those products but my baby is in pain and it’s heartbreaking to watch.
