Sound machines are a lifesaver when you have a newborn. You will do just about anything for more restful sleep as a parent and these will do the trick:
-> Marpac Dohm Classic is a must have for every kid's bedroom. This one has been around since 1962 - no bells and whistles - just the sound of loud rushing air that will drown out any disturbance and soothe your little one to sleep.

-> Marpac Hushh is an amaizng portable option. Operates for an entire night on one charge or just throw it in your bag when you are on the go.

-> The Baby Shusher is a godsend in our house. Set the timer to 15 or 30 minutes and let it do the work for you, shushing your baby to sleep with a real human shush. Seems weird, works wonders.
