Pumped milk for daycare

I go back to work next week, my daughter will be 12 weeks old. I’m stressing about sending milk to daycare. She has had bottled here and there when she’s been away from me (maybe 10 times) and done fine with them. She has drank anywhere from 2 - 4.5 ounces at a time. My concern is when we are at home she nurses anywhere from every 1 to 4 hours. I know a lot of it is probably for comfort but I can’t send 8 bottles with her to daycare! I was thinking to send 4 bottles of 3.5-4 ounces each. She tends to not eat as much when we aren’t at home. Not sure if that’s normal or not. She will be at daycare 8 1/2 to 9 hours per day. Any insights?
