When I first announced I was pregnant, the first thing other parents told me to do was buy a fancy bassinet called a SNOO. The SNOO’s magic is that it detects the baby’s sounds electronically and rocks itself as needed so you don’t have to.

“If you can swing it, it’s the best money you’ll spend,” one new father told me. Another mother told me that after purchasing the SNOO with her second child, she slept “at least one hour more a night, sometimes two” than with her first.
