Chicken soup (make noodles separate), beef stew, fish in foil pouches with citrus/herbs... lots of things can be made dairy-free.

Pasta without cheese or dairy? I LOVE spaghetti squash with meat sauce (not cheese required).

Slow-cooked beans are also fantastic.

Soups and stews are good, she can just throw them into the crockpot to warm up. Also, I made shredded chicken burrito's with pinto beans, onions, and peppers for my new mom friend. I didn't add cheese to them because they were eating lowfat and she loved them. You could also do breakfast burrito's without cheese.

Chicken Tortilla soup is hearty. You could do meatloaf muffins (individual servings) or homemade meatballs/marinara sauce.

Just because her first child developed a milk allergy doesn't mean at all her second will, so I don't think you need to worry about leaving out dairy (unless she specifically requested it)

I love pesto (minus cheese, if need be) you can whip up a huge batch in your food processor and freeze in small disposable plastic containers so all they have to do is boil some pasta and toss with one of the containers worth. It's a ton of meals, no mess and super yummy.

I made chili (not too spicy) and cornbread muffins for a friend, which were super easy to freeze and reheat. My friend's only complaint after her daughter was born was that her visiting family loved the food so much that she barely got any!

chili with cornbread or black bean soup with a small loaf of homemade bread. Additionally desserts like blueberry or apple muffins and brownies!

Ditto the chili-stew train of thought. I made a huge batch of way mild white chicken chili to freeze before my 8mo old came (your friend might have continuing heartburn/hormonal aversion to strongly flavored foods). Do her a big solid and make a "lunch" batch by portioning it in 1-serving sizes, not 2- or 4-. Red beans and rice also freeze very well. Freeze the rice separately. Also, don't underestimate the power of a simple, well-seasoned pot of beans. I ate and still eat lots of bean salads for the healthy protein boost, and they're easy to make if I can pull the beans from the freezer.

Beans, lentils, tomato sauces, and shredded meat all come to mind. Raw or par-baked pizza or stromboli with nondairy cheese. Cooked steel-cut oats can be frozen in portioned blocks that she can throw in the microwave for a quick breakfast (or dinner, if she's like me).

you could make homemade pasta sauce - if you portion it out in smaller containers, she should be able to take out just what she needs when she needs it. homemade is always better than a jar, and you can make a lot of different meals with pasta sauce.

Bread...to go with all the soups and pasta dishes.

That's so thoughtful of you! What about shepherd's pie? You could make it with lamb or turkey instead of beef, if you're worried about the cow's protein allergy, since for many sensitive babies it includes all cow products, not just the milk. Moosewood Restaurant Low Fat Cookbook has a recipe that uses the water to boil the potatoes instead of cream in the mashed potatoes, but you could easily sub your favorite non-dairy milk product for a richer taste.

Unless she has requested, I don't think that you need to leave out dairy. Odds are her next child won't have a dairy sensitivity (which is what is what is she was able to eat dairy after four months) and she won't be on an elimination diet.

But, to answer your question, I'd worry more about the kid than the mom. I always find getting the rest of the family fed more stressful than getting my calories. So, I'd make sure that whatever you pack is super-kid friendly. Cheese bechemal (like for mac and cheese) frozen into ice cube tray for a fast hot lunch; shepards pie; white bean and sausage soup; etc.

This is really sweet of you! I second the shredded meats. I do a shredded bbq chicken in the crockpot that freezes beautifully.

You could also make a batch of freezer burritos like the ones at Shutterbean and just omit the cheese. Just try to add something else creamy/moist to makeup for it, like avocado or extra salsa.

i've made granola recently for new moms, and it's been really well received because it works well for breakfast or an anytime snack.

agreed with the soups and stews. a hearty lentil and chorizo soup with kale would be great winter soup that's also super healthy.

Thanks everyone! These are great. I'm going to be stocking my freezer as well as hers!

Great suggestions - I'm getting some great ideas for my own freezer.

For my pregnant friends, I always do pulled pork. The recipe I use is for pulled pork tacos, but it also works great with carolina sauce and coleslaw for pulled pork bbq sandwiches - I usually deliver it with the fixings for both to stretch it for multiple meals for the family.
