Hi,
It is very stressful to have to contemplate going back to work when your heart is telling you you need to be with your little one.
However, your breastfeeding relationship need not suffer because of this. Many women return to work and keep breastfeeding just fine. For a start, you can breastfeed as normal when you are with her. Most employers are very happy for mothers to express and in a hospital you will find they probably have facilities set aside for this. By the time you go back to work your little one will be on solids - so the pressure is off to some extent. Won't take a bottle - well, no-one said she had to. She can take her milk quite adequately out of a sippy cup, or a straw cup. Or really, take a packed lunch and bottle of water while you are away. On the other hand you will need to express so you are comfortable enough to work!
Personal anecdote - I returned to full time work when my baby was 6 weeks old and he fed til he was over 4 years old - so combining work and breastfeeding is definately achievable.
