Glad I found this thread!
Halloween costume: Thank you, O universe, that M wants to be a black kitty cat. She already has a black turtleneck, black leggings, and I miraculously HAPPENED on little black and orang kitty ears on a headband at Walgreen's the other day, that she miraculously actually finds comfortable to wear. She's been practicing (and practicing and practicing) her tiny, high-pitched kitty mew, and pretending to scratch the furniture with her tiny kitty claws. If I get it together by the time she needs it, I may make a tail, but I don't think it will occur to her first to want one. And we'll use black marker right on her face (whoo-hoo!) to make whiskers and the tiny kitty nose. She loves drawing all over herself with marker, so that'll be a thrill.
BTW, her first Halloween, when she was 7 months old, she was a little purple cowgirl, with some purple cowgirl boots I happened on in Old Navy.
Birthday efforts: For the last two years, we have made it a specia adventure to go to the local megamarket, for her to choose her own birthday cake for them to make, and then more fun to go pick it up the day of the party. She knows that her Aunt D makes all her own birthday cakes, but so far does not judge her own Mommy as a slacker who does things the easiest way possible.
Food, Pickiness around: M is pretty good about eating a pretty wide variety of fruits and vegs. (Katherine, I was thrilled to hear you have a vegetarian, Miranda is too.) And doesn't really know a whole lot about candy yet, just that it happens at some special events we go to. She still accepts what I told her once, that all the candy displays in the grocery store are "big kid" candy. I can't believe she hasn't argued that one yet. She also knows that at dinner, if she wants more mac & cheese, I will say, "Sure, have two more broccolis while I get it for you." And she eats the brocs. She's not at all compliant in some regards, but the food thing is usually okay.
We have a family coming over tonight to join us for dinner, and when I called the mom to ask what would make a successful meal, I found out that their little 3 year old will only eat spaghetti with butter and cheese, and that cauliflower is her only vegetable. So that's what I'm serving (with sauce and other things on the side).
MY cringe: M started preschool a month ago, and the teachers tell me she sometimes doesn't act like she hears them when they direct her to do something. "Have you had her hearing checked?" they asked. Um, no, I'm pretty sure she has the ears of a bat, considering she yells, "Siren! Siren!" about 30 seconds before I can hear it approaching. It's just that her Mommy and Daddy aren't always very, you know, consistent with followthrough when we ask her to do something. So she's not used to being as cooperative as a preschool full of kids might require her to be. So we are working on that.
