I've basically just been in your position...had a baby in October when my 1st was 2.5. I wanted to do the same thing. My mom came to visit and made a huge pot of spaghetti sauce and meatballs, which we froze in meal size containers. (Freezing the meat separately to pull out what we needed for each meal.)
We used to live up in the Tampa area and went to a place called Dinner Done. You go and prepare 8 to 12 meals at a time, which are then frozen for you to use as you need. On the whole, I don't like freezing cooked meals, then defrosting and reheating. Just not very tasty to me. So, I really liked this place because you freeze prepped meals and then actually cook them. So, 2 things about this place that could help you: pretty much all of their meals follow 2 basic cooking instructions. Either they are stored in ziploc bags which you thaw completely in water first and then either grill, saute or put in the crockpot. The other method has you cooking the dish in the oven on 350F, covered for the first 30-45 minutes, then uncovering and cooking another 30-60 minutes. I always use a meat thermometer to get the right doneness as their times tend to overcook in my oven.
It is so awesome to be able to just open up your freezer and pull out a the main dish of a meal and pop it in the oven or quickthaw and put it in the crockpot. You would still need to add fresh veggies and possibly a starch, like rice. The 2nd thing about this place that I wanted to mention is that they now deliver to all of Florida for $25! Instead of going there and prepping your dishes yourself (unless you were in the area, I guess), they prep it for you for an extra fee and now they deliver. Unless you think you will have to be 100% dairy free when you breastfeed (as I am now), it could very likely work for you. And the cost is reasonable. Plus, they do not do a bunch of casseroles, which similar places do. Their website is: www.dinnerdone.com. We probably got food from them 4 times both towards the end of pregnancy and the first several months. My parents would drive it down for me since they didn't have delivery then.
Since I do have more dietary restrictions now with the baby, I have opted not to order the food again quite yet. But I have discovered some crockpot dishes that aren't soups/roasts that I like. I actually cook a bit of chicken in it. I will put in a few pounds of chicken breasts to make bbq or taco meat. It only takes a few hours on high, so you don't have to remember to do it 1st thing in the morning. Then I shred the chicken (or chop it up). For the bbq, I season it with a bbq rub and add some water. For the taco meat, I might add the taco seasoning and half the water it calls for. (Alternately, for tacos, I grill up the meat and then heat the seasoning packet and water up on the stove, chop the chicken and add it to the sauce. I just prefer this to chopping the raw chicken, then browning, etc.)
Another thing that my mom made for us that we froze were potato pancakes. I would just thaw them a little and either put them on the grill with whatever meat I was cooking or put them in the oven for a quick reheat.
Another nice thing about the Dinner Done meals is that they ARE from scratch. You make all your own sauces when you go there, etc. One dish that I have the recipe for from there is a General Tso's chicken. The sauce is super yummy, and my mom put all the ingredients together in several meal portions in ziploc bags and then I froze those. When we made the meat part at dinner done, we took diced chicken, rolled it in panko bread crumbs and then put in the foil cook pans. When it came time to cook, you put them in the oven (I usually transferred to a cookie sheet), and it makes a nice crispy chicken 'nugget'. My daughter doesn't eat heat up chicken nuggets either, but she likes these.
I like to really cook too, but with 2 kids and a rough delivery recovery, it has been helpful taking advantage of these tools. You are smart to think ahead! Hope you are able to fill your freezer with food that will make the transition simpler. Congrats!
