? about food & formula

My daughter is almost 6 months old (on the 22nd) and has been eating food since 4 months. We started her on 1-2 times a day (2-4oz), but we were told to get her on a 2-3 (6-8oz) times a day schedule. So once I did that she went from 30oz of formula to 22-26oz of formula a day. I’ve always fed her as she was hungry and stopped when she told me she was full. I don’t know how many oz of formula she’s supposed to have when she’s eating 6-8oz of food a day. Should it still be at least 24oz? She’s healthy and gaining weight. There aren’t any medical issues or concerns. I’m just curious if she’s having enough when it comes to formula. Any advice?

Edit:

I feel I should probably mention that she’s also teething so maybe that has something to do with the lack of appetite? 🤷🏻‍♀️
