9 month old not drinking formula anymore

As the title says, my 9 month old isn’t interested in drinking formula anymore. I’m lucky if I get her to drink 4 ounces. Most of the time it’s 2oz. I feed her twice a day if puree and give her water with both meals, but I’m just so worried about her. She’s also getting over a cold so I know fluids are so important but she’s just not interested.

Anyone got any tips?

I’ve tried adding oatmeal/rice cereal to formula, I’ve tried doing more frequent smaller feeds, I will soon be going to the doctor for her 9 month check up but it’s still a week out and I don’t want her to suffer until then.

So any advice is appreciated 😭
