Ironically, we flew to the U.S. on January 30, resetting our internal clocks. But I guess you could say it was the perfect final "exam"! :)
Surprisingly, both kids slept well while we were in the U.S. Sophia did not have her usual "happy hour" in the middle of the night. However, this meant that she was waking very early the first few mornings and I got to experience what so many parents of early-bird toddlers complain about. I went to sleep early, but still found it hard to get up early. Even when we started sleeping a little later, I found myself prone to morning melt-downs. I'm definitely not a morning person! And I also wondered, is there something wrong with ME or is it just a matter of whether the crankiness happens in the morning or afternoon?
Now that we've been back in Russia for a week, Sophia is starting to sleep better. However, this is thanks partly to my meticulously planning and limiting her naps. It is counter-intuitive for me to do this, but it has gotten her sleeping at night again. While she had fought her second nap for several months, I finally learned that is it actually the MORNING nap that should be dropped, making more awake time in the first half of the day rather than the second half. I also read that there should be about 4 hours of awake time between the last nap and bedtime. We'd been doing it the opposite, napping earlier and then crashing an hour or two before bedtime. I think we're on the right track now!
