The safest way to reduce milk production is to do nothing but nurse baby on cue (meaning whenever baby wishes and, in a addition, offering to nurse anytime you feel the desire to nurse) and wait while your body figures out it is making too much milk and makes the adjustments on its own. Milk production takes energy so your internal biology will eventually act to reduce any over-expenditure of energy. Unless the body gets a different message due to pumping over and above what baby needs, over production reduction should gradually and entirely safely happen all on its own.
Block feeding is the best method for reducing over production, because it is simple, adjustable, and works. If you think you need to take active steps to reduce milk production, this is what you might try, starting with very short blocks at first. Also remember this method really works, so no need to do it more than a few days, typically. Before even considering block feeding, I strongly suggest read this article: http://www.nancymohrbacher.com/articles?tag=Block+Feeding
Some moms just are leakers and some are not, and there are actually many benefits to leaking, because moms who leak are less likely to become engorged, develop serious plugs or come down with a breast infection. Leaking does typically reduce over time. But leaking alone is not an indication a mom makes more than enough milk.
