Hi, we did something similar to the pp just before DS turned 9 mos and it worked great. We actually never dropped below 3 oz because he started refusing his dreamfeed completely when he dropped his late afternoon catnap and we were able to move supper a bit later. So instead of [supper at 4:15, catnap from 5:30-6, bottle at 6:45, asleep at 7:30, DF at 10] we moved to [supper at 5, bottle at 6:30 and asleep at 7].
