Once you've settled on a type and have considered your range, you can look at the potential choice and which features they have. The more budget-friendly choices usually lack bells and whistles but are still functional. If you want more features like nightlights, lullabies, and talk to the baby, then you may pay more and the unit could be more difficult to use. The one feature we think is important is sound activation to help keep your device quiet when your baby is quiet, thereby increasing your chances of a full night's sleep.
It really depends on what you feel most comfortable with. There are audio monitors that allow you to listen to any noise coming from the nursery, vital monitors that track sleep and breathing and video monitors that add sight to sound. Babylist parents overwhelmingly choose video monitors. The security of seeing what your child is up to—like if they’ve gotten tangled in their swaddle, pulled their diaper off or climbed out of the crib—can be worth the extra cost of a video monitor.
