How many inches makes a ruler?????

The one at our house is 25 1/2 inches and her name is Kate the Great! Just kidding--she hasn't mutated into a total dictator, but she has been a bit more demanding lately.
We're not all that sure what happened. A few weeks ago, all was well. Kate was sleeping through the night, napping during the day. And then, BAM! She changed all the rules on us and we've been trying to figure things out (again) ever since. I know, "It's just a phase," "this too shall pass," and all those other mommyisms. Bottom line, being a mommy is tough work sometimes. But, then again, the pay off is HUGE!
