Leave it to a frustrated and sleep-deprived mother to develop a fuss-free swaddle that can comfort a baby back to sleep. Karen Barski's third child was born five weeks early and just couldn't get on a sleep schedule. As a nurse, she knew the importance of swaddling, but the baby ended up in a heap of blankets each night. So she sat down with her grandmother's sewing machine and made the Woombie, a soft yet snug cocoon-like swaddle that simulates the sensation of being in the womb. After seeing how it comforted her daughter, she launched Woombie as a product ($25) in December 2007. Since then, babies have slept a bit more soundly, leading to more rested parents.
