How to get rid of the sippy cups?

Well when I wanted to get my daughter to sleep in her own bed the doctor just told me to let her cry it out. And not to get her anything to eat or drink to get her to go back to sleep because then you will always have to do that. Just let him cry and after a few nights he will know you're serious and not getting him the cup. If you crack and get it for him the only thing you're teaching him is that if he cries long enough you will eventually give in to whatever he wants. Just be strong and he will learn that mom means business and 4 am is not the time for chocolate milk. Good luck!
