Maybe you can try using nipple shields when you're nursing your baby now. This will make her get use to the taste and feel of silicon or aftificial teats and by the time you have to go back to work, she'll be more susceptible to bottles.
Another suggestion I can offer is trying out the bottles by Adiri. It literally looks like a breast attached to a bottle. I've had friends who used this bottle and they find it worth the price (can be quite pricey).
