Need help mommas

My daughter turned a year old on the 10th and a couple weeks before that we had been slowly transiting her off formula and a bottle. She only gets a bottle with formula before bed now and we are planning on stopping that once we run out.

Since this her fluid intake has gone way down. I don’t know if it’s the milk or not using a bottle but I have to constantly off fluids and it seems like she’s hardly drinking anything. I’ve tried different temps, different cups, I’m kinda at a loss. She doesn’t seem to mind the cups she just doesn’t seem interested in drinking.

I’ve tried milk, water, and apple juice cold and room temp and still not a whole lot of interest.

She is still having wet diapers but not nearly as many as before.

Anyone gone through this and have any tips?

We are seeing her pediatrician tomorrow for her year appt but just wanted to get thoughts from moms who may have gone through this. We have tried 2 different types of straw cups and the Nuk sippy cup.

Thanks ladies
