Timma,
My advice is
1. relax, the more anxious, the less breast milk
2. the baby drink both side might because of her need for attachment and security but not hungry
3. let her eat as much as she can, as our body produce milk according to the demand of the baby. Actually BB is helping you to build up the your quantity of breast milk.
4. I started to reserve milk for my baby 2 weeks before going back to work. I pumped milk after each meal of my baby. When you go back to work, there will be some 'stock'. So don't worry.
