We've been reading Elizabeti's Doll by Stephanie Stuve-Bodeen and illustrated by Christy Hale. I love this little story of Elizabeti's desire for a baby of her own and her creative problem-solving. The kids enjoy it, too. First Daughter's been asking to carry her new baby around just like Elizabeti.
Apparently there are a few other books featuring Elizabeti, but I haven't read them. Are they as sweet?
