I need help, my lo will drink water and juice out of a sippy cup no problem, but when it comes to her milk she MAY drink 1oz out of sippy cup, then will either refuse it and want to go off and play or will refuse it and start crying and hitting the sippy cup out of her way. I then go and put the rest of the milk in a bottle and as soon as I bring it out she is all over me to give it to her. I've tried Playtex, Avent, and Nuby (the ones that resemble the bottle the most). She knows they are not her bottle and will throw a fit over it.
