One minor but potentially annoying flaw: The “on” lights on the parent unit of the Infant Optics are a touch bright, and you may be more sensitive to them because you’re likely to have the unit within view as you sleep. They appear as greenish yellow light from the face of the unit, and a charging light, which is blue when the monitor’s fully charged. Depending on how sensitive you are to light, you may want to lay the display face-down on a nightstand or cover the status lights with tape.
If you sleep in the same room as your baby or live in a small enough space that you can always hear or see what your baby is up to, you probably don’t need a monitor. Otherwise, most parents enjoy the convenience a baby monitor provides—instead of needing to stay close to the nursery or constantly checking on your child, you’re free to rest, catch up on Netflix or get things done around the house during naptime. Monitors can also double as a nanny cam to keep an eye on your child and their caretaker.
