Several people asked about the brunette twin's favorite color. It is still purple. Nothing changes there and I don't expect it to for a while. Of course, she could surprise us, but she is just not a child who changes easily.
Her favorite doll is a stuffed bear she received as one of her first critters. She has other, newer dolls and stuffed animals. She plays with all of them, but the bear is her favorite.
She doesn't like to change. She likes things just the way they are. I expect that she'll happily keep purple as her favorite color for a while.
