Will you just pee for us, baby?

We are waiting to get a urine sample to show that he has enough fluid so we can start chemo. With almost a whole bag of IV fluids and almost a whole bottle of water, he still hasn't wet his diaper ( we put cotton balls in the diaper to collect urine). Maybe he will pee for us when he wakes up.
His ANC is 924 this morning, compared to 200 last Monday. Platelets above 500 and hemoglobin 9.6.
