Watch this parent share why this sleep trainer is one of their “best parenting hacks” in this TikTok. 

Promising review: “My 2-year-old started getting up at 6:30 instead of 7:30 and was ready for the day. I saw this on TikTok, so I ordered it and explained to him how if Mella is red, we have to sleep, and when Mella turns green, it’s time to play. The first night, he sat up a couple of times in the night, looked at it, and laid back down. We’ve been using it for almost a week, and he stays in bed until it’s green without any crying or complaining, so it fixed my problem so fast! You do have to toggle the night light on to red if you want it in all night. You could choose other colors, too, but red and green worked well since he has a car seat with red and green stop lights, so easy connection. Anyways, I highly recommend it! He loves to check on Mella during the day and see if it’s asleep.” —Mpt2
