BUT if you want to continuing to breastfeeding, have you tried pumping a bottle to feed him before bed? Could be that giving him an extra large breastmilk bottle does the job to get him to sleep, too. (This worked for me, but not for that long because pumping is the worst, IMO.)
OP here. We have been giving him a bottle before bed of bed of breast milk and formula. His last feed is at 10/10:30. He woke up at 1am, 4am, and then 7am. He slept all the way through to the 4am feed and then twice to the 7am feed when he was on formula.
