It can be so confusing, can't it? A few things to think about...not sure what time you're planning to do lunch, but make sure it's early enough in the day that you can watch for any reactions or issues that the new food may create. You can always do breakfast as the first meal if lunch is too late in the day. Once you've gotten going with the first meal, it's up to you how quickly you add additional meals. Some wait a few days, some wait a week, some wait a couple of weeks. There's really no right or wrong answer on that one.
As for nursing, you can certainly keep it up as long as you wish and it will be enough to sustain him. I'm not sure when they stop "needing" breastmilk...it has different benefits at different ages. Whole milk can replace breastmilk or formula when your DS turns 1, so if you decide to start weaning him much before then you'll likely need to start him on formula (unless his dr approves starting whole milk early, but most won't even consider it until babies are at least 9 mo). Keep an eye on how many times per day he nurses (it should still be at least 4), his interest in nursing, and how long each nursing session lasts. You don't want solids to take the place of breastmilk or formula for several more months.
Post back if you have any more questions!
