Breastmilk question

Hello mommas!!! So today im going on a date with my hubby, ive been pumping after breastfeeding my baby for 2 days to leave the bottles to my mom who is the person that is going to babysit my baby, so ive been put in every breastmilk i pumped into a bottle and keep filling it until it gets to 3 oz. I filled 2 bottles like that but they are not from the same pump. And the milk is from 2 days ago and a day ago and today, is it om for my baby to drink it?
