Who is the Mother of Invention?

There's a famous saying by Plato, “Necessity is the mother of invention”. Well here is a list of inventions by mothers in need of answers to some practical childcare problems:

- Ann Moore invented the Snugli in 1969
- Ruth Handler created the Barbie Doll in 1959
- Sarah Neal invented the folding crib in 1894
- Adeline Whitney invented alphabet blocks in 1882

Inspiration for inventions can come from many sources, but it stands to reason that great ideas are to be found from just recognizing what would improve our own daily lives.
