Amy,
Brianna wouldn’t eat her baby cereal with milk for some reason either, but she will eat regular cereal (cheerios, kix, whatever) that could be worth a try. Also, we just always make sure Brianna has a sippy…one with milk in the fridge and one with water where ever she is playing. I used to offer them to her a lot, but now I don’t becuase she knows the sign for milk so if she wants it, she just lets me know, and the water is always out. Good luck!
