I have been giving my baby breast milk since day 1, I've gone back to work and I wanted to try and give her both breast milk and formula  but she doesn't like the formula..  I don't know what to do.. I can only get about 6oz  every time I pump.. So by the time it's time for me to go to work I only have like 3 bags of milk and she eats a lot.. I don't mind pumping milk on my lunch break every day. But what can I do to get her to start drinking formula?
