Bottle advice - stressed mum 🫠

My lg is 8 months (7 adjusted) on Sunday. She has 4x 7oz bottles a day and 3 meals. She always drank all her bottles until around 4 weeks ago and now never finishes a bottle. I have cut down on her meal portions, taken away a meal and it has made no difference to her milk intake. Some days we are only reaching 16oz. I have tried dropping a bottle making this 3 a day and she did drink more of her bottles but we still only reached around 19-20oz. Her first bottle of the morning she is now only really taking around 3-4oz and has NO bottles overnight which I just don’t understand she must be starving 🤔 I’m at a total loss on what to do and so worried about her overall daily milk intake as I keep reading this is meant to stay the same until they are 1 as food is for fun but she just loves food. Is anyone else having this? Have you implemented any changes that have helped? She will drink water in the day, only small sips and current bottle schedule is 7.15am 11.15am 3.15pm 7.15pm
