When I lived in the desert I had to feed the baby additional water. Water tastes bitter to the baby. I put in a couple of drops of honey to take the bitter away. See if you can get her to take the bottle if you rub a drop of honey on the nipple. I know a lot of people are furiously against honey, so boil it first if you like. A drop or two of honey will not upset her.
Keep introducing it, it'll come. It's not that uncommon for breastfed babies to refuse the bottle at first. I know it's frustrating, but try not to give in. It's important to get her comfortable with the bottle.
There are nipples you can get that do a really good job of mimiking the feel of the breast nipple. Look into some of those. And remember, she won't starve herself. Instinct will kick in. Oh, and if you are able, pump for the bottle as opposed to using formula, at least at first. I would start with breast milk in the bottle, then if you decide to, switch to formula once she is used to the bottle.
Best of luck to you!
its best to breasffed her but if your going to work its best to bottlefed when your at work and breastfed her at night.
