Erin, I hesitate to recommend this because it is not exactly the "BW" way, but I work full time and pump and try to get as many sessions with ds as possible so, I thought I would share what I did. At thee/four mths I was on a 4 hour EASY.
I did a df at 10pm, another df at 6am (dh sleeps from 8pm to 8am), ebm at 10, ebm at 2pm, bf at 6pm.
When the df at 6 am started to not work as well (around the time we should have been dropping to 4 feeds) we changed the schedule to df at 10pm, ebm at 8am, ebm at 1pm and bf at 6pm (I get home at 6pm).
Then, at 9.5 mths I dropped the df (later than bw recommends but it worked great for us and I really loved the df). So, we were left with ebm at 8am (I pump at 7:30 right before work and dh feeds him), ebm at 2pm and bf at 6pm. Now we are at two feeds (8am and 6pm).
Hope that helps as a slightly alternative schedule.
