Baby has milk protein allergy. Help!

I recently learned that my newborn has a milk protein allergy which means, since I’m breastfeeding, I need to cut dairy out entirely from my diet and holy cow, it’s in everything!

I need some advice on how to make this transition. It’s been difficult because I forget about things like bread, quick frozen meals, the coffee creamer that I thought was dairy free (I know), etc. and I’ve come to realize just how much dairy I consume on the daily.

To make things harder, I live in the southern U.S. and I feel like we use butter for everything down to writing utensils.

So, if any of you have tips, advice and brands of alternative and dairy free products, please share!
