Hi Stefanie, Congrats on your baby! Going dairy free means you need to carefully read labels for any hidden dairy. This resource is helpful: https://kellymom.com/store/freehandouts/hidden-dairy01.pdf
For breakfast, some dairy free ideas include oatmeal with fruit/nuts mixed in; scrambled veggie eggs; avocado toast with hard boiled egg slices or tomato slices on top; whole grain cereal with berries and a non-dairy milk; toast with peanut butter and banana slices. For lunch, things like canned salmon salad (made like tuna salad but without the mercury!) on bread; chicken salad sandwiches; crackers with hummus and veggies; lentil or bean/veggie soup with whole grain bread, etc. For dinner, you can make big batches of things like rice and beans with peppers and onions; grilled meat with roasted potatoes and veggies on the side, salmon or white fish with roasted veggies and quinoa, bean or meat chili, burgers with roasted potato wedges, etc. There's actually a LOT you can eat, and it's a little easier to focus on the foods you can have when planning meals.
