I had 3 awesome kids too! : )
I have to admit that I hyped the "big boy or big girl" cup. That worked with my oldest. My middle child was sold when I pointed out that his sister was using a cup so he wanted one. My youngest weaned at 12 months and never went to a bottle. I just made it sound pretty exciting so that they dropped their bottle like a hot potatoe. I have found that the child who breast-fed longest drinks milk the least... I wonder if there is any correlation. Good luck with this one.
