Quite a bit, it turns out. Rosemary is tired of being the center of attention, having 6 names, and never having a special person to play with. She envies her neighbors and friends with siblings to whisper secrets to, argue with, make messes with, and go home together.
Her parents just can't understand why she's upset and don't seem enthusiastic about having additional children...so Rosemary comes up with her own unique solution.
The illustrations show Rosemary moving from smothered only child to the messy, not-so-lonely person she wants to be. Her stubborn determination is evident from her perky pigtails to her wiggly mouth.
A fun - if somewhat unrealistic - story for anyone who's ever wanted siblings - or wanted to get rid of them!
Verdict: It's not quite the thing for storytime - I've tried it and it just doesn't work. But parents might like to try the reverse psychology approach if they have a new sibling on the way!
