Your feeding schedule looks great! What a great little eater you have. First off I would say hold off on the juice if you can, not only is there really no need for it, it can cause tooth decay once his teeth come in and it has a lot of excess sugars (natural at that) but it still raises the childs blood sugar. The nutritional value of juice is less than that of the real fruit, so I would just keep giving him the fruits from the jar. If you are going to give juice, give only a little during meal time. Water is great all the time around, it does not cause tooth decay as well helps prevents dehydration and constipation. Just be sure he is not drinking too much that it fills him too much for his bottles or food.
At that age I introduced the mild, very healthy veggies like sweet potato, carrots, squash and peas. Green beans are a good starter food too, but they don't have as much nutrional value as the "orange" veggies. Ella still loves her "orange" veggies.
It sounds like you are doing a great job!!!
