One of the first things I did with all three of my kids when they were first learning to drink out of a sippy cup was to teach them how to cheers. The babies loved it because they could bang their cup against your cup and usually it would make a cool sound if you were using a glass. I further incorporated the word "cup" or "cheers" each time they would drink. Heidi has really taken to this and when sitting at the dinner table will repeatedly say cup until I pick up my glass and cheers her. She won't redo it until I actually drink however which lead me to think that I could really use this to my advantage by creating a drinking game called Drink Baby Drink!!.
My years of study at ISU taught me that when someone "cheers" you you have to drink so it is only natural that this came about. In Drink Baby Drink there are only three rules: You have to drink when your baby cheers your cup. You have to drink if the baby says cup or what you think is the equivalent to cup. Thusly, your baby will get you drunk in no time. Heidi only really says "cat" and "cup" so I am good to go. Oh, and the occasional "dada" but I think she is just trying to get my attention to pick up my cup.
