Parents who want to both hear and see their baby will naturally opt for a video monitor. Video monitors are particularly great for those with older babies learning to stand in their cribs or toddlers transitioning to a bed who'd much rather play than sleep. They're also a good pick for parents who need to keep tabs on more than one child, as many video monitors will allow the parent unit to toggle between multiple cameras.
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.
