I think what you're describing is normal for her age, from what I've been told here lately. I also give my LO 8 oz formula/milk feeds in the morning and before bed. She also gets a mid-afternoon bottle with cookies as a snack. However, we only give her water with solids. My LO also doesn't seem to interested in the water in a sippy cup, but she will drink it out of a bottle. We just keep giving it to her because eventually she's going to have to figure it out. She also like drinking water right out of a cup with no lid with my assistance. We have issues with dehydration, too, which is the only reason she's still getting the afternoon bottle. Once she figures out how to drink from a cup, we'll drop it.
Also, my LO is also sometimes refusing food at dinner. I don't really know why, but I don't worry too much about it since she's at a good weight.
