first and foremost, dont panic, baby will sense that and will be a bit freaked out too.
baby might not take a bottle from dad if you are in the room, or even the house. try to leave for a while, even for a walk, or grocery shopping, whatever, and see how he does.
most of all, let him do it all by himself. the only way that your husband can find out how to calm your baby and figure out how to work things out is if you just go somewhere between now and the time you go to work, and let dad fend for himself. its HARD, and NO ONE could possible take care of her like you do, but thats not a bad thing, and its good for her to know her dad this way. they are going to become so close because of the time they will spend together, and the easiest way for your husband to get ready for it is to do it! :D
good luck. :D your husband sounds great!
