8.5 month old refusing milk

My 8.5 month old has been giving us the hardest time drinking milk. The goal is 24oz per day, we’re lucky if she even gets to 20oz. I breastfeed when I’m off or she gets bottles when I’m at work. Either way she gives us a hard time. She’ll drink 2-3oz (from 4oz bottles) then stop and not want anymore. We give her 3 meals a day, 30min after her milk so that the main focus is on milk. We even skipped a meal to see if she’s drink more milk but she’s just not into it. Does anyone have any recommendations?! We called the pediatricians office and they just said to make sure she tries to get 24oz per day 🙄 as if I didn’t already know this. Any advice appreciated!
