Hi E., Do not worry abouth this. My daughter was the same way. She was never really a "mouth" baby, what I mean is, she would never take a pacifier, she had a very hard time changing from my breast to a bottle, and she never put things in her mouth even when she was teething. I would buy the teething rings and try to show her how to put them in her mouth, and she would make the funniest face, and push it away. When it came time to start giving a sippy cup, she would just play with it, and hardly drink out of it. I just continued to give it to her, and slowly she started to drink out of it. She always preferred her bottle though. By the age of 2 she was just drinking out of her sippy cup. One thing I remember is that in the beginning she did not understand the sucking part, so I took the spill proof gadget out and then gave it to her, in her high chair ofcourse, and she seemed to do better. Just keep offering it, she will get the hang of it. I would just switch her during the day to a cup, and still maybe the bottle or breast at night, then go away with the bottle and just the cup. Hope this helps.
