First I am not 全泵型的奶媽, I used "邊泵邊餵" and switch from "Medela Mini" to "medela Swing" to increase milk supply from 5oz to 7oz. I think "邊泵邊餵" is the best especially when 谷奶 in the morning, really have a lot of milk, ie. 6oz for one side ga..
Which pump you used? Also as Hellocandy said 用手鍊 when pumping is also help.
