My LO dropped BF cold turkey at 7.5 months. I had previously pumped every morning (she only ever took one side and I had to pump the other for comfort!) but when the wean happened I only pumped when absolutely necessary for comfort, and my milk dried up within a week - it was a much quicker process that I expected, as I'd planned to drop a feed at a time. I had a bout of mastitis a few weeks before this so was super careful! I think if you wean gradually there's no reason why you can't drop from 4-3 feeds, give it 3 days+, then drop another feed, leaving the morning and night feeds as the last ones to go.
