When it came time to prepare the food, it was pretty easy. I peeled and then chopped the potatoes and carrots. I sliced off the ends of the green beans, chopped them in half and then gave them a good scrub.
Then, I boiled the vegetables (separately) until they were soft, and then pureed them in a Baby Bullet (blender - thanks to my SIL Katie who gave me that for Christmas last year!)
I purchased a bunch of small containers - 2-3 oz each - that are freezer, fridge, microwave and dishwasher safe, and had those handy to spoon the pureed veggies in to. After the cooled down, I moved them to the freezer and - voila! - 24 individual servings ready in a flash.
Scott and I haven't decided when we will start Jacob on solid food (save for a serving of single-grain oatmeal he had a few weeks ago) but it will likely be in the next few weeks. Can't wait!
