How do you start bottle feeding?

Po
My job has very generously let me work from home and come in 1 day a week. My husband will be watching DD. How do I start with a bottle? I've been saving milk but just hate the idea of her having to use a bottle :( she's a super nurser! I don't know if I trust my husband with this so we'll be practicing...ha. I have no idea how much she eats! 2 months old. Any tips?
