Time Change.

I must say, despite losing an hour of sleep, I like springing forward much more than falling back.  (I would use "technical" terms here, but I have to say that I have no clue when we are in "daylight savings time" and when we are not.  I just change the clocks -- or rather make sure Buck has changed the clocks -- when the calendar dictates.)  Reason?  Better schedule for Fawn.  Fawn is getting up AFTER 7 (a true spring miracle), and napping at 1 instead of noon.  Falling back with toddlers is for the birds (who wants their day to start at 5 am even if you get an extra hour of sleep?). 

The scientific math:

Bad schedule for Fawn + extra hour of sleep = no fun for even a well-rested mommy

Good schedule for Fawn - one hour of sleep + extra cup of coffee = very happy mommy
