I am a first time mom of a 2 year old and my son wont seem to go without drinking his cup at nigh. And he will only drink milk or juice every time I try and give him water he wont take it just gives me his cup back. Last night he cried so loud from 2am-am non-stop. I am worried he may not take to this new way and I am not sure how to go about it should I continue to allow him to cry like that or just give him his cup when he wants it.
