Do other people's kids talk like this?

The Peanut has developed a very distinctive speech pattern where she puts a lot of emphasis on certain words. I keep trying to figure out where this comes from, and I now suspect she is imitating us when we speak to her and, without meaning to, emphasize certain words she's having trouble pronouncing or whatever. This weird emphasis thing, combined with the usual 3-year-old tendency to jump very quickly from topic to topic, is a scream when she goes off on a monologue, as she often does when we're in the car. Also she says "Mama?" after practically every sentence to make sure I'm still listening. So she sounds like this:

I wish we could just FLY to school because then we'd get there faster. I wish the car had WINGS. But we'd have to be careful not to make too many turns or I'll BARF again. I hate it when I BARF in the car. Mama? Did you know people can SHRINK? Yesterday Owen said when he and his cousin went in the ocean when they were on vacation, they went all the way to the bottom and they SHRINKED! For REAL, Mama! And then when they came out of the water they UNSHRINKED! I wonder how they did that? Mama?

I don't like pink anymore. Now my favorite colors are purple and teal and KUR-QUOISE. Kur-twoise? Quor-quoise? That's a hard word to say. Maybe we can find me a superhero Halloween costume with ALL my favorite colors in it, even QUOR-TOO-QUOISE. Maybe we can get a little superhero costume for Mainey (the Peanut's teddy bear--full name: Main Teddy. It's a long story). She can have a little cape and we can FIGHT BAD GUYS! Mama? Can you make Mainey a little tiny superhero cape? That would be SO CUTE!

Mama? At my birthday party I get the PRESENTS, right Mama? And everybody else gets the GOODIES? Do we have goodie bags for the party yet, Mama? Is it October yet? It's my birthday SOON, right? Mama?
