We are on vacation and attending a wedding this weekend. We've left LO, who will be 6 weeks on Sunday, a few times but just an hour or two here and there. We are now feeding exclusively breast milk after supplementing until 4 weeks with formula. When he was supplementing with formula, it was an ounce to 2 ounces here and there, and now it has been only at the breast. So I have absolutely no idea how many pumped ounces to leave per bottle for while we attend the wedding and leave LO with my parents (who have come on vacation with us specifically to babysit their new grandson!)

We will be at the ceremony from 2:30-4, so I will feed him right before we leave. We are staying very close to the ceremony site, so we can come back to the house to feed him again before attending the reception. We plan to be at the reception from 5-8 or 9ish. How many bottles of how many ounces would you leave at this age? I know every LO is different, and I know I should leave more than I think I will need, but I would love to have a ball park--fitting in time to pump during this trip has been hard so I need to make sure I fit in enough sessions before the wedding tomorrow! Thanks for any input
