When my wife and I brought our baby home, an Owlet monitor was one of the tools that helped ease our new-parent anxiety. If you’re in the same boat, Amazon’s Prime Big Deal Days sale is a good time to consider one. The Dream Duo 3 is $299.99 at Amazon, an $80 discount and one of the lowest prices we’ve seen this year.

The Dream Duo 3 is really two monitors working together. The Dream Sock slips onto your baby’s foot and uses pulse oximetry to track pulse rate and oxygen levels while they sleep. The FDA has cleared it as an over-the-counter monitor for healthy infants ages 1 to 18 months who weigh 6 to 30 pounds. It’s FDA-cleared, and if those readings drift outside the ranges you’ve set, the base station lights up and sounds an alert.

The second piece is the Dream Sight camera, a 2K HD monitor with a 130-degree wide-angle lens and 4x zoom, so you can see the whole crib day or night. It supports two-way talk, picture-in-picture, and background audio, and it tracks room temperature and humidity. You can control the sock readings and video feed through a single app, making it easy to adjust settings and see what’s going on.

Owlet also supports what it calls Predictive Sleep Technology, which suggests wake windows based on your baby’s age and patterns to help you build a routine. The sock tracks up to 18 months, while the camera works well into toddlerhood, and you can pay to unlock deeper insights like sleep trends and a morning report through Owlet360, available for $9.99 per month. On the privacy front, the camera features a cybersecurity certification and 256-bit encryption, and the whole kit is FSA- and HSA-eligible.

The Dream Duo 3 system depends on a solid Wi-Fi connection, and the sock needs to be positioned correctly, or you may get false alerts. Believe me: nothing will get you out of bed faster than an alert, whether it’s false or not. The Dream Sock is not intended to diagnose or treat a medical condition, and it does not replace adult supervision, safe-sleep practices, or advice from your child’s doctor.

For many parents, though, an extra layer of reassurance can help you get a more restful night’s sleep. When you’re in the thick of it those first few months, a few extra minutes of sleep make a huge difference.
