I'm having majoy problems with my supply..My baby is 7 weeks old and the first 4 weeks were fine. She got all breast milk, with only maybe an ounce of formula here and there for the first 4 weeks.

Now she is eating about 5 ounces at a feeding and I am only able to pump one ounce at a time, so the other four ounces she gets are formula. I am feeling extremely guilty and like I have failed. Should I just give up on the pumping and only give her formula, or is even a small amount of breast milk worth it for her?
