My 7 month old won’t drink milk anymore

Hi everyone so I’m a ftm And starting to get worried. My daughter started on purées about a little less than a month ago and she’s been doing very good with it but, she has stopped drinking her bottles (breast milk). I struggle to get her to drink the milk. She’ll take the little apple juice the sitter gives her I give her a little water but struggle quite a bit to get her to take the milk. Has been going on for about a week. I’m not sure if it’s that she’s been eating purées or I thought could also maybe be that her first tooth is finally starting to break through the gums.

Has anyone had problems like this with their littlest? What did you do

Update:

We buy the gerber purées and she’ll eat about an ounce or two once or twice a day so never more than 4 ounces a day. And the juice was started because she had gotten constipated and the pediatrician had said we can give her some daily to keep her from getting constipated again. So the sitter will give her a couple of ounces while she’s with her then once home strictly milk with the occasional water

I did exactly what the pediatrician had said even with the solids, we just had a check up and she said to continue doing exactly what she had said. 😢
