Can't sleep either

It is 2:30am and Regina's been tossing and turning and rearranging pillows for a good hour now and has finally fallen asleep, but here I am wide awake after all of it. We had another ultrasound today and he's head down and with his back to the left--which is the perfect position. I watched the chambers of his heart open and close and his ribs squeeze in what the doctor called practice breathing.
