Re: Decreasing milk supply
Welcome to the forum and congratulations on making it through the first challenging weeks!
Most moms start out with some degree of oversupply. It's nature's way of making sure the baby (or babies, just in case you're nursing twins!) gets fed while he masters the tricky art of nursing. But oversupply comes with a downside: making extra milk is a waste of energy and puts you at increased risk of plugged ducts (which you experienced) and mastitis. So eventually your body "reads" the fact that your baby doesn't completely empty the breast and reduces milk supply to a level which is better matched to the baby's needs. Once this adjustment occurs, it's normal to rarely if ever feel full, to leak less or not at all, to feel reduced or no letdown sensation, and for baby to act fussy at the breast as he gets used to the new flow pattern.
Now, on to the question about how you can get the baby to feed "regularly" or every 2-3 hours. The answer is "You don't". Your baby spoiled you a bit in the beginning, giving you such evenly spaced feedings. But that sort of feeding pattern is unusual in early infancy, and nursing frequency can be expected to jump up "during growth spurts and when an increase in milk volume is required" (as the American Academy of Pediatrics puts it). At 6 weeks, you're likely experiencing the big 6 week growth spurt- so lay in some snacks and water and park yourself on the couch with the remote control or a novel, and just nurse, nurse, nurse. That's the best way through this period. You don't need galactogogues and you don't need to pump unless your baby's diaper output drops below normal or he stops gaining adequate weight.
One mistake a lot of first-time moms make- and this includes me- is feeling like they need to wait for their breasts to "refill" in order for the baby to have a "satisfying" nursing session. Not so. The breast is never actually empty, because milk is always being made, and it's being made faster when the breast is kept empty. Full breast = slow milk production, empty breast = rapid milk production. And while the permanent latch-on can be exhausting, it's also the best thing out there for increasing supply.
The one thing I would review at this point is your birth control choices. A lot of moms start contraception after their 6 week postpartum visit, and if you chose hormonal contraception that could be putting a damper on your supply.
