Hooray! We decided to give it a try on Monday because they weren't really fussing for it, I was just giving it to them according to schedule. (We work according to schedule because to do everything on demand with twins . . . you'd go nuts). We've made it 3 days with no complaints! I feel like I can actually go out now because I don't have to worry about that bottle, and naps are done with by that time, so I can actually do some running around now. They're still getting 18 oz., and the pedi said we could get down to 16 by their birthday, so we don't have to worry about them getting enough.
