My lo has reduced her oz and it’s driving me crazy. I usually do bedtime like 830 9 she will either fall asleep on the bottle with only have eaten 3 oz or just diesnt want it! So she is then waking up 2 hr later hungry then her whole night is screwed up. What am i doing wrong! When will she just sleep throughout the night. Is there something diff i should be doing with her naps n bottles
