Hi B.,
Is your husband giving her the bottle while you are home? If so, I'd have him offer it while she can't see/hear/smell you. Also, I'd have him offer the bottle before she is crying, she's desperately hungry at that point - have him look for earlier hunger cues. I'd ask him to be sure to warm the nipple of the bottle, and to smear a little pumped milk on it, so that she immediately knows that she can smell and taste right away that she's getting what she always eats.
It's normal for babies to take less milk than normal when mom is away/back at work. When I went back to work at 11 weeks when my last child was born, the first day, he took one pumped bottle, the second day he took two, and the third day, he took 3 which became his norm. It's also really common for babies to eat less while mom is gone and then nurse more when you are at home.
Good luck !
