Re: not pumping as much
I think that stopping the bottles is okay if your baby is nursing well, getting at least 2 oz per feeding on average. Do you have a lactation consultant, preferably an IBCLC, available? She could check you and the baby out, and figure out if things are going well. If not, maybe you could rent a professional baby scale, and do some weigh-feed-weigh tests (weigh baby, feed baby, weigh baby again, making sure baby is wearing same clothes/diaper throughout) to determine how much he's taking in at a feeding.
If you feel like the baby is getting hooked on bottles, a supplemental nursing system like this one may help you keep the baby at the breast for all feedings, eliminating the need for the bottle. (You would want to nurse the baby first, ensuring he got the maximum directly from the breast, and then give the supplement at the breast.)
He's really still a week from being a full-term baby, so I'd be cautious... But maybe some of the moms who have experience with preemies will weigh in with some more informed comments!
