Infant eat, wake, sleep cycles are measured by the beginning of one feeding to the beginning of the next. This is not something I made-up - apparently there are "experts" who say so.
Anyway, Noah had gotten himself on the 3 hour cycle I mentioned in a previous post. In the past 48 hours he's had a few longer cycles and has seemed to have self adjusted his cycles. He ate at 8:45 PM last night, slept and didn't wake until 1:45 AM!!! Woohooo!!! Then he slept until 5:45 AM and again until 8:45 AM!!! I don't even need coffee today!!
