Think of your produce department and the freezer section of your supermarket. Where would you find cut up fresh cubes or pureed products. Just about every veggie is the frozen section has been blanched or cooked for you. All you have to do is thaw and finish cooking. Fresh cut up foods are found in your produce department. Those foods require more work.
And to give you some peace of mind, you won't be in the hospital that long. Not even for a C-Section. Forty-eight hours for a normal birth and five days for a C-Section. So hubby is not going to starve while you are gone. He will be spending most of his time at work or the hospital. He can always eat in the hospital cafeteria.
