V.C.
try getting to use a STRAW... and if he see's you throwing away the bottles.. and DON'T bring them out at all he will have no choice, he knows he still has a choice.. it is the same thing with using a pacifier... they may fuss and cry but it isnt going to hurt them I promise, it is more of they like trying to control the little things that they can... whcih are big things to us. ;) I nursed but I have gone through this with pacifiers, and other things at one time or another.
If and when he is thirsty and wants a drink he will drink from whatever you have available... he may pitch a fit at first but you could tell him he is a BIG boy now and big boys use sippy cups/straws/ regular cups whatever you decide to use but NO BOTTLES... it is much easier than you think as long as you don't give in those first few days. :) Maybe think about colored straws but make sure you use some white ones too...
