The concept of sleep revolving around when the sun comes up or goes down had already passed even before Kai (Chika and I both lived in Finland where days can be dusk in the winter and nights could be neverending dawn in the summer).  But the new sleeping schedule is something which can’t be easily reckoned with, especially as it suddenly switches on after birth.  Kai has been pretty good.  He does 4 hour stretches sometimes, and sometimes will head back to sleep after a meal and a change.  However, sometimes he just feels like being a nightowl, and wants to hang around with mommy and daddy.  Those are the hard ones.
