I went the hard love route, and just started offering Archie greens alone, after a couple of days he wolfed them down. Sometime I would mis some mixed veggies in with the greens, and that way they minimally get a few pieces of green stuck to the veggies. In general though, Archie was not a really picky eater. He has actually gotten more picky as he has gotten older. Both my Uros really like collard greens and mustard greens, but dislike turnip greens. Once I started cutting up bits of other things into their "salad greens" such as zuchini, and apple, they dive right in. My baby was a good greens eater right from the start, thanks to Lindsay, and will not touch the mixed veggies at all. So you basiclly have two options, ween your Uro onto the "Better stuff" particularly greens, or go cold turkey, and eventually he will be hungry enough to try it.
