reverse feeding please help

My LO is 7 months old and she has solids 3 times a day and it's not a whole lot at a time , well since January when I started back to work she was turning 4 months but she still woke up during the night to have a bottle well when she hit 6 months she hardly would have a bottle at the daycare ( which is mother in law) but would have several  when I was home with her or the weekends this past week she will not take a bottle at my MIL she waits till I'm home to eat so she like cluster feeds. I'm conflicted my doctor said stop giving her solids until she starts taking a bottle but I think when she starts taking a bottle how do we work solids back in? Also we are closer now for her to stop using formula and eating solid food as a source of her main eating instead of the formula, so I'm worried when it becomes time for her to cut back on bottles she won't want to and that will be a fight too. I'm one tired mom she eats about 5-6 bottles between 6pm and 6am and none during the day
