I now believe even more in persistence & patience. When I started the 1 nap routine, after just 1 day, I almost gave up.
Thanks to the support of DH and encouragement of few mommy friends, I persevered.
I am now starting to enjoy the fruits of the perseverance after 1 week. Isabelle is adapting well to the routine. Of course, occasionally, she still gets up just after an hour of nap instead of 2 hours which is the ideal duration. It does upset my daily schedule & chores, but I reminded myself that she is just a human (and not a robot on timer). All I needed to do was to tuck her in to bed earlier to compensate the short afternoon nap.
