Since Catherine transitioned from 2x2hrs and 1x1hr to 2x1.5hrs over the last month i have been wondering when another transition will happen? She has always slept 11-12 hrs since 2/3 months and also wonder when she will drop her night sleeping as well as currently she goes down at 7pm and wakes up between 6.30-7am. You see i wasn't expecting her to drop to 2x1.5sleeps for another month so i want to prepared for the next transition.
