2-3 oz at 11-12 weeks

Iria
So Mommas I am almost 12 weeks ppt and via pump can only get 2-3 oz frim both breasts. Baby takes the breast and bottle is still hard to take for her but she gives in and drinks from it atleast once a day. She takes the breast and after she is done she lets go and then we switch sides. Is 2-3 oz enough? She is 10 lbs a lil more maybe she was born 6lbs.
