So I decided to breast feed right now my baby girl is on formula as of now but I want to switch her to breast milk But my boyfriend mom said I have bad milk right now I have to wait until the milk is white to give to baby girl

I didn’t know yellow breast milk was bad

So as of now I been pumping every 3-4 hours dont get much milk how can I produce more milk ?

Can you guy educate me a little on that yellow breast milk being bad milk ?
