Bottle feeding.

My husband wants me to start bottle feeding. She eats much quicker and goes to sleep quicker with the bottle. Still breast milk though. I get his point because at night when I nurse she'll eat for ever. And won't go to bed until maybe midnight. And be up at 5. She's 5 months old. I like the bonding but I miss sleep. Anyone else exclusively pump and bottle feed? How did it go?
