L.H.
Definately correct her whines with words. If she brings her cup too you and whines look at her and ask her what she wants.Pretend too put a banana in a cup and so on until she gets some words out of what she wants. She also may whine because of the new baby, she sees/hears a baby whine and cry and get attention she may be a little smartie and trying it out for size :)
