Oh my gosh, DD2 is absolutely "the destroyer"! And she is so *quiet* about it. You turn your back for 2 seconds (or go to the bathroom, or blink or..) and she has completely trashed an entire room. I sat down to work with DS6 with school one day with her running around near me, I realized she had been quiet for a minute and went to check on her- she had opened the refrigerator, taken out the flour and spread it all across the kitchen floor. I was literally 10 feet away from her, just not in direct line of sight.

She's only 2 (in 3 days) so I can't say for certain, but she seems to be more GT than the DS6 and DS4. At barely 2 the boys knew a lot, but it was just regular preschool knowledge, early. She seems much more active and self-directed in her acquisition of knowledge- she explores because those are the things she wants to understand, she takes things apart to see how they're made, she tears things up to see what happens. She just seems to have a more mature understanding of the world than the boys did- for instance, she would never run into the road because she gets that the cars are big and she's little. At 2 both boys were still giving me heart attacks in parking lots, despite constant talks about the dangers of running in the road. They would say things like "I'll tell the car to stop and it won't hit me!". She gets that it doesn't work that way.

But, I swear, she's going to make me go completely gray before she's 5!
