(Mental Floss) -- With Mother's Day just around the corner, this week seemed like a great time to give a tip of our caps to stay-at-home moms, including these four who used clever ideas to become business moguls. 

Gerber: Of course only a mother could found such a successful baby food company! In the late 1920s, Michigan mom Dorothy S. Gerber was hand-straining food for her baby daughter, Sally, when she realized there must be some way to avoid the messy task. 

She pointed out to her husband, Daniel, that if his family's business, the Fremont Canning Company, could puree a tomato all day long, its equipment could probably make short work of other fruits and veggies, too. 

Daniel Gerber realized his wife was on to something, and after a year of experimentation -- and an extensive search to find the right drawing for their label's now-iconic "Gerber baby" - the Gerbers introduced their first line of baby foods, a super-yummy menu of strained peas, carrots, prunes, and spinach.

Baby Einstein: When Alpharetta, Georgia mom Julie Aigner-Clark went looking for educational materials for her newborn daughter in 1996, she found a disappointing hole in the baby market: there weren't really any educational materials to expose babies to music and the arts. 

Some parents would just accept whatever the market was offering. Not Aigner-Clark. She shot a video for her daughter in her basement then edited it with her husband, Bill, on the family computer. She even doodled a logo for the video at her kitchen table.  QUESTIONS:
