Question on 8 month old breastmilk amounts

Hi breastfeeding moms, I've been exclusively breastfeeding my baby since he was born and he has started solids but is not very keen on them. His number of feeds have gone down to 5 before he sleeps. 3 of them are 5 oz bottles and then j feed him twice on the boob so amount unknown. He wakes up a lot during the night and I'm thinking of giving a bottle. For Moms who exclusively pump, how much milk are you giving your 8 months old in a day? Baby is 23 pounds if it helps!
