I'm going to an event in a few weeks and will be leaving my EBF baby from 6:30pm til 11:30pm. In that time she might have anything between 0 and 3 feeds on a normal night. She's never had a bottle before and I have no idea what volume of milk she usually has. I'm pumping to leave bottles in case needed. How many ounces do you think I'll need to leave? Is 18oz likely to be enough to be really sure she won't run out?
