Dairy free breastfeeding fav foods!?

Hey there! I realized the day after some very important ice cream that my little man does not tolerate dairy. Its the whole shebang… fussiness, constipation, excessive spit up etc. I have decided my dairy days are over… at least for my breastfeeding career. But I am going crazy with my sweet tooth! Anyone got some yummy easy recipes or walmart suggestions? Smoothies are my life saver right now but I’m hoping for more suggestions from other mommas who had to go dairy free
