I thought about plaguing you with a foggy-headed haiku celebrating the wonder of a full night of sleep. Instead, I’ll make a short observation and hope that it’s coherent.
I once heard that the optimum sleep cycle was a short four hour rest followed by six waking hours and so on. The argument was that such a cycle would increase productivity.
Obviously, this person never had a newborn.
Take note: 2.5-3 hour sleep cycles X 2.5 weeks = So. Very. Tired.
