I second all that has been said about pumping. You are doing the best thing for your babe!!!
DP breastfeeds DS, but I am home with him most of the time, as she is a fulltime teacher. We had HUGE challenges with the bottle, but I wanted to report some strategies to you and mention that he has been a very solid bottle feeder ever since she "really" went back to work in September. I count him a hero for it and her an even bigger hero for pumping!
We practiced with the bottle every day once we figured out DS hated it. We would try and when he got upset, stop, so that he didn't have a bad association.
We used an orthodontic nipple. Something about the shape was easier for him at first. We later transitioned to Avent. I advocate buying as many different nipple shapes as you can to see what DD might prefer.
We often started out by putting a bit of the breastmilk on our finger, letting DS suck on it, then pulling out the finger and quickly slipping in the bottle. He then got the same thing from the bottle. This seemed to work on occasion.
We also tried dripping milk from the bottle onto DS's lips to get him into the milk, the giving the bottle.
The best method, however, was having my mother give him the bottle. She was SO calm with DS, not nervous like we were that he would never get it. Her patience was what did it -- he took the bottle with her for a few days straight during a family vacation, usually once or twice a day. I'd highly advocate having a non-parent try with DD.
Finally, just be persistent. Try on weekends, even though you're home. DD will definitely get it. When DS was with me and I thought he was hungry but didn't take the bottle, I wore him in a carrier, which was always sure to sooth him, as I think often he just wanted the soothing of breastfeeding, not the nutrient side of it. I'd urge DH to use some sort of carrier to help sooth DD.....
mostly, know that you are doing the right thing and DD will surely get it.
best of luck!
