Hi C.,
At this point, it really doesn't matter what or how much she gets. The majority of her nutrition will be coming from her formula/breastmilk and that will naturally taper off in a few months when she starts to be more interested in table foods. I never really bothered with baby food with my four children. I would cook fresh vegetables in a small amount of water and then blend them in my food processer. At this stage, when she is not eating a lot at a time, you can make this and freeze it in small containers. I always think that baby food stuff never really tastes natural. As far as the sweet potatoes go, you can bake a couple, scoop out the potato, and mash with a fork. They are much tastier than jarred sweet potatoes.
When she has worked her way through most of the veggies, you can make this stuff that sounds yucky but tastes pretty good. In a small pan, put raw hamburger, a handful of rice, and all the veggies she will eat, and some that she won't (carrot, green bean, cauliflower, broccoli, peas) and cook with a small amount of water until the rice is very soft. The hamburger will be cooked through as will the veggies. Put the whole thing in the food processer and blend until slightly chunky. Add a dab of butter and a dash of salt. Every one of my kids absolutely gobbled this stuff up and it has three food groups to boot! If it is too runny, add a little rice cereal to absorb the extra liquid.
Just a side note. ALL the jarred baby foods that are mixed meals (beef stew, macaroni/hamburger, turkey/noodles) are not credible on the USDA food program for daycare providers so we cannot feed them to our kids as they don't provide enough nutrition. I think people feed their kids this stuff thinking they are giving their children balanced meals (I know I did with my first one) when in fact, they are nutritionally incomplete. They are convenient but they are not nutritionally sound. Your best bet is to cook for your child from scratch.
Good luck!
