My almost 9 month old has been taking bottles with no problem at all since she was 6 weeks old. My mom watches her while I work and gives her 3 bottles. Just this week DD has been refusing the bottle. She also will not drink the milk from the sippy cup. The milk has not changed, I tried a faster flow nipple, different bottle and nothing is working! She is not acting fussy, but is possibly teething. She will eat solids and drink water without a problem. I called the doctor and she didn't have much to tell me besides keep trying. Any thoughts on this?? She is going on day 5 without any milk during the day!
