I may just be an unlucky exception, but I wore breastpads until LO was nearly a year old. The leaking did reduce dramatically from the early days, when I had to change pads all the time, to being able to get away with using just one or two sets a day after maybe 3/4 months or so? And around 8ish months I swapped to the re-usable Avent ones, which at the beginning would soak through in no time, hence were completely useless in the beginning for me. Hopefully you'll be much luckier than me though.
I'm 13 weeks pregnant at the moment and really not looking forward to the whole leaking thing again, especially as breastpads here are ridicilously expensive.
