Even though the jury is still out on the effects of EMF on the human body, this doesn't mean parents need to wait for more definitive proof before making thoughtful adjustments that err on the side of caution. Given that exposure compounds over time and with an increased number of devices emitting, you can help limit baby's exposure by turning off devices when they are not in use, unplugging wireless routers at night while children sleep, and keeping products as far from your baby as possible when in use. Even if you are not convinced that there is potential for harm, it certainly can't hurt to make choices that potentially increase the health of your home.

The longest battery life for the dedicated products in our review is the Levana Lila, which ran for 12.75 hours in full use mode. The manufacturer claims this unit will work up to 72 hours in power saving mode, but we only tested the monitors in full use. The Infant Optics DXR-8 came in second place with a shorter run time of closer to 11.5 hours. The Motorola MBP36S earned the lowest score for battery life with a runtime just under 7 hours. While not necessarily a deal breaker, there are plenty of other reasons to dislike the Motorola MBP36S, and the battery life is just a small part of a disappointing overall picture (no pun intended).
Baby monitors are just one way to keep track of your little one. For newborns, the Snoo Smart Sleeper is a bed that gently rocks your baby for better sleep, and connects to an app on your phone that lets you receive alerts when your little one needs attention. The Owlet Smart Sock 2, meanwhile, is a connected pulse oximeter that allows you to check on your baby's vitals any time through an app, and will notify you automatically if there's a problem. The Sproutling from Fisher Price is a motion and heart rate sensor that straps to the back of your baby's calf and collects data while he or she sleeps.

Traditional video baby monitors don't offer the same high-resolution picture quality we're used to seeing on our smartphones and tablets. If you want high-resolution video of your baby, you'll have to go with a Wi-Fi monitor like the NestCam that streams video to your phone or tablet. The Phillips AVENT SCD630 video monitor may not be high-res, but it's the best of the bunch.
Our testers preferred the Baby Delight’s parent unit — its buttons were more responsive than Angelcare and it was easier to set up. This movement monitor uses a cordless magnetic sensor instead of a pad. Because the sensor is clipped onto your baby’s onesie, right next to their chest, the alarm won’t go off if you forget to disarm it before a middle-of-the-night feeding.
The MPB36S has everything you might want in a video baby monitor. You don’t have to squint to see your baby because the LCD screen is a large 3.5 inches and shows a clear color picture. Alongside the screen, there are buttons that let you pan the camera from side to side and tilt it up and down to see every angle of the room. The zoom feature lets you get up close to make sure your baby is safe and fast asleep. You can soothe your baby by choosing among five pre-loaded lullabies or talking directly into the microphone.

Gone are the days of silently peeking into the nursery to check on your napping baby and then, whoops, accidentally waking them up (“No, no, please no!”). A baby monitor uses a camera to watch over the crib, while you carry a handheld device that lets you know what’s going on with your child at any given moment, no matter where you are in your home. There are also other monitors that track sleep or breathing either with a clip or sock.
