She's increasingly capable of remembering and reasoning about her own emotions. Her reports of her preschool mornings consist of who she played with, what they did, and whether anyone was mean or bossy to her. The common threat at this age is "If you don't [play what I want] I won't be your friend any more" and it is a very present and scary threat to Morgan. Even though she doesn't have independent contact with any of her friends they are very important to her and she thinks and talks about them when they're not around.
She's having a hard time dealing with Tori getting more attention, and spends a lot of time pretending to be a baby too, or wishing they were twins.
She still won't admit she can read, because it's hard and puzzling out words does not result in anything like the pleasant story flow of being read to. She can write, though. She usually wants the nearest grownup to spell out each word for her one letter at a time, hEr OrtHograPHy lOOkSSS LiKE thiS, and sometimes she takes several stabs at a particularly tricky letter or runs out of room left-to-right and takes off in a random direction or starts somewhere else entirely -- or all of those, which can lead to particularly inscrutable collections of letters if you weren't watching her write it down in the first place.
She's quite good at simple addition, and subtraction as well if she's got paper to jot hashmarks on for counting. She can write all the digits from 0-9. She still tends to skip 15 when she's counting.
She colors inside the lines; draws faces with eyes, noses, mouths, and sometimes hair; draws stick figures with arms, legs, and occasionally hands. She's gotten much more willing to just take a stab at something even if it doesn't come out exactly like she wanted.
