Hello there! Welcome to the boards!! Congrats on BF this long too!
I know what it feels like to be anxious about the weaning thing.... Specially if he uses the breast to fall asleep! My story is posted on the toddler sleep board and I think you will find it useful.
Anyway, about the milk... he doesn´t really NEED it if he eats cheese, yogurt, etc... he probably won´t take it because he is not used to drinking cold milk... and if he takes the sippy cup with water, that´s great! My dd never took the bottle and loved water. She did like milk and still does but if they eat right, they don´t miss much if they do´nt drink it.
I hope I´ve helped you some! :wink:
Know you are not alone ok?
HUGS!!!!!
