My only suggestion would be that you go for diversity, and make sure your meals aren't too focused on the same few ingredients -- especially the ones that are commonly associated with allergies and sensitivities (milk & soy products, eggs, tomatoes, heavily spiced dishes, etc.). It's not uncommon to hear about nursing babies
having trouble with certain foods in the mother's diet. Food sensitivities can also affect postpartum mothers themselves, with all the raging hormones and whatnot. After having my last baby, I developed a weird reaction to tomatoes (they made me break out in hives), and it turned out that just about all the main dishes I'd frozen had them as an ingredient. We ended up with a freezer full of food that I couldn't eat.... which, needless to say, was no fun at all.
This time around, I'm going to play it safe, skip the mixed dishes entirely, and just freeze the "basics" in meal-sized portions, e.g.:
- pre-cooked, plain whole grains and beans
- meat patties, fish fillets, natural sausage and ham, cut-up chicken
- pizza crusts
- shredded cheese
- chopped green vegetables
- cubed squash & root vegetables
- chopped onions, garlic, & pesto, frozen in ice cube trays & stored in a bag
That way, we can throw them together as necessary.
If you don't have a tendency toward food sensitivities in your family, you might not need to go to such an extreme, but it would still be good to try for variety. Maybe, in addition to the gumbo and chili, you could make some goulash (which traditionally uses paprika instead of tomatoes), or a chicken casserole, or a big batch of split pea soup.
