When your 2.8yo, still in diapers, is conducting a self-toilet training experiment in urinary output.

DS' Method:
1. Request 3oz of water. Ingest quickly. Urinate. Request diaper change.
2. Repeat step 1 in full, requesting on each turn 3oz of: orange juice, cow milk, and breastfeeding.
3. When breastfeeding, pop off the breast to "verify" you are getting 3oz. (Ha!)
4. At the end of the experiment, ask which beverage yielded the highest fluid output.

Not perfect, but pretty good for a 2 year old.

What is to give light must endure burning.
