As a baby, T slept 10 hours on the button. His morning nap was 1.5 hours and his afternoon was 45 mins-1 hour. He slept basically 12.5 total hours in a 24 hour period.

R seems to sleep a little more...though he doesn't STTN, he usually sleeps 11 hours total (with one waking). His naps usually total 3 hours, too. His naps are inconsistent, but he naps longer overall usually!
