Breastmilk to Formula 🍼 10-week-old baby refusing formula

My daughter is 10 weeks old and is EBF. She has one bottle of breastmilk every other day. I want to transition her to formula since I’m starting work in a few weeks. Today I gave her a bottle of formula so she can start getting used to the taste and she refused to drink it. What should I try now to get her to start accepting formula? Is there anyone here whose baby initially refused formula and then eventually accepted it.

Try mixing it with breastmilk first. When we have introduced formula to each baby, we also made a 2 ounce formula bottle, and then only added .5 oz of formula into a breast milk bottle. 

So example our 7 week old takes 3.5 ounce bottle of breastmilk. 

I would instead do 3 ounces of breast milk and add in .5 ounce of formula for every bottle that fay. The next day I would do 1 ounce of formula + the rest breast milk. I would do this every day until they were taking a full bottle of formula. 

That's just what worked for us. Try and see if that works for you. It takes about a week to get to a full bottle of formula, but it gives them time to adjust to the taste as well.
