sleep...?

Jax is currently 3 weeks and 4 days. We are trying to get him to sleep at night, a concept he obviously has never quite understood. This is becoming more and more critical as my minuscule amounts of sleep keep compounding on each other, just like one big sleepless nightmare. We listened to tons of advice and tried tons of different things--nothing worked. AND THEN...last night, thanks to some very recent advice and Justin's lack of patience we very well may have hit a break-through. We just let him scream. Then he fell asleep. Magic.
