What do you ladies recommend as far as how many bags should I have to feed the baby throughout the day? I am running a few errands soon and will leave my daughter with her father (fingers crossed everything goes well 😂😅) but I have few bags frozen and still going to pump today. The bags I have are the Medela storage bags. I didn't fill them up to 5oz. The most I have on one is 4oz and the lowest I have on one is 2 1/2 oz. She is a month and 10 days old.
