How Many Sippys?

One of my biggest challenges at work is getting kids to drink. Based on a child's weight, there are so many ounces one should drink in a 24 hour period. Hardly any kid reaches that goal while they are in the hospital let alone a normal, healthy child. Well, except maybe Tanner. He is my drinker. It's kinda hard to tell, but Tanner is actually holding 3 sippy cups. Here he has milk, juice, and water all at once. He is rarely seen without at least one sippy cup under his arm like it's a football.
