Sound machines
Momcozy Portable White Noise Machine
Our take
A cheap rechargeable sound machine with 20 sounds, a night light and a child lock, small enough for the diaper bag. Sound quality isn't as rich as plug-in machines.

Consider instead: Yogasleep Dohm for the nursery.
Before you buy
Do you need it?Nice to have White noise helps many babies and parents sleep, but it's an easy add later if you need it.
Cost per monthAbout $0.69 a month over a typical 36 months of use. Our estimate; your use may be shorter or longer.
Secondhand?Fine secondhand. Fine secondhand.
TipKeep it across the room and at a moderate volume rather than right next to the crib.
