Book from my childhood about growing up.
I have been wanting to find a book I remember from my childhood in late 60's or early 70's that has left a lasting impresson on me. It' has wonderful illustrations. A brother and sister go out to play and start talking about what they want to be when they could be when they grow up. They talk about being a lion tamer, animal doctor, nurse, that's all I can remember. I would like to find it so I can read it to my grand daughter. Thanks for any help you can give. :)
