Last night was kind of successful!! There wasn't a big difference to the piece of cucumber I put in, but there were parts where you could tell he had been on it sucking on it :3 So I am trying again tonight with some fresh zucchni from the garden and hoping maybe he will gradually realize it's some yummy stuff. But I will have to try the yams. That is one I haven't heard but I am up to try anything to get my little guy his food.
