Formula intake

My daughter will be 11 months old in 10 days, but she was on 3 sippy cups a day, now she seems to be wanting a lot more formula so now she’s on 9 oz. for each sippy. Should I wait to let her wean herself to 2 sippy cups or try to do it now? The doctor said between 17-20 oz a day now since she’s eating more food but with 3- 9oz bottles that would be 27 oz which seems too much for this age right? She does eat 3 meals a day with snacking in between lunch and dinner. Or should I try to give her more food/snacks instead of her wanting a bottle in between her morning and evening sippy? I’m a FTM so I have no idea🤦🏼‍♀️ I don’t want to not be feeding her enough or taking away any nutrients and I want to make sure I’m doing this right lol. Please help😂

Also please feel free to comment any healthy snacks or meals down below that your littles eat!!☺️
