KatelynsMom, I often think of you and how you describe Katelyn... yes, there is a lot of mental growth (and her legs grew!) at 25 mos. DH and I are having some trouble characterizing it. It doesn't seem to be easily quantifiable like how many words can she say sort of thing.

I called a preschool to discuss enrollment and was discouraged to learn that DD will not be allowed into most 3 year old preschool classes until Sept. 2010, when she'll be nearly four, cry since she's a December baby. They mentioned the jump from "parallel play to cooperative play." Well, she's in full cooperative mode.

Last week we went to the bank and DD made a bee-line to another toddler who was there with her parents. "Hi, what's your name? Want to see my baby doll?" she said. They sang the alphabet song together and took off exploring the bank while everyone in the building watched. At one point, the other little girl, age 3.5, said, "She's not sharing" so we patiently explained that DD 25 mos. is still young and does not have any siblings to share with. DD looked at me, looked at the little girl and said, "Oh. I'll share. Here you go, would you like this?" and proceeded to play the rest of the time in full share mode.

So that's what we really see, I guess, interpersonal stuff, imagination, playing make-believe for hours, scary memory, and making logical connections. Am I making any sense?
