What's the earliest book you can remember reading (on your own)?
I remember reading all of the Mrs. Piggle-Wiggle books: Mrs. Piggle-Wiggle, Mrs. Piggle-Wiggle's Magic, Mrs. Piggle-Wiggle's Farm, Hello, Mrs. Piggle-Wiggle, and Happy Birthday, Mrs. Piggle-Wiggle. I never realized they had been around since 1947.
Everyone loves Mrs. Piggle-Wiggle. She lives in an upside-down house and smells like cookies. She was even married to a pirate once. Most of all, she knows everything about children. She can cure them of any ailment. Patsy hates baths. Robert never puts anything away. Allen eats v-e-r-y slowly. Mrs. Piggle-Wiggle has a treatment for all of them.
The series was written by Betty MacDonald.
