my DD also 6 in November has suddenly started asking for Baby Annabell. I am really unconvinced how long her interest will last, but she has stuck with this request for about 4 weeks now. Other threads on MN do talk about children playing with baby dolls up to age 11, so perhaps there is some more mileage in it.
