Although I try not to talk too much about my kids (foibles or successes), I know people like to hear how Liz is doing. Plus, this is a good place to keep track of things, since, like most #3 children, she does not get documented as much.
Just this week, instead of blithely accepting whatever I pull out of her drawer to wear, she said, "no" and pointed to a different shirt hiding at the bottom. First time she's ever shown a preference for clothing! It was kind of fun. :)
So, two things that have helped a lot around the house. First, Liz started using possessives about two months ago. I remember we were doing laundry, and she pulled out a sock and said "Luke sock!" and another, "Mama sock!" It's so nice that she can recognize possession, because it makes the whole sharing thing (marginally) easier. Actually, I take it back. We still really struggle with sharing.
It's made a much bigger difference at the table. For example, she used to finish her food and then fuss/whine/reach for whatever she saw on other plates. Now, when she finishes her blueberries and wants mine, I can say, "These are Mama's blueberries, where are Lizzie's?" She'll repeat what I say or say, "Tummy" (which is where her blueberries are!), and we can generally distract or move on from there without descending into a tantrum.
We have also been working a lot on two-step processes--first cut the food, then eat it; first drive home, then you can have baby doll; fill the bottle, then have it. Liz is beginning to understand the whole idea of two steps, but I think she is also trusting that we will fulfill what we say.
