I researched sleep trainers several months ago when my 18 month old began regressing and waking up between 4am and 5am every single morning. I tried altering bedtime schedules, but nothing was working and I was becoming more and more exhausted (and desperate!). I found a similar product, but I hesitated to buy, as the unit had to be set up manually on the unit. Also, it gave 3 colors indicating sleep, quiet play, then ok to wake. My daughter knows her colors, but I wasn't confident that this would be easy enough for her to understand quickly. I gave up, and another 2 months passed with no improvement. I decided to look again and found the Hatch Baby Rest. I somehow missed this product on my original search, and I am so sad that I did. I decided to take a chance, and this thing is absolutely amazing! It took a few tweaks to get the best setup for us, but the options are truly limitless. The app is fantastic and intuitive and can be set up in minutes. After several weeks of use, my daughter sleeps til around 6am, and I am still slowly pushing it later bit by bit. She completely understands now that if the light is off, it is time to sleep and mommy comes in her room when the light is on (green, in our case). I have also been able to remove her sound machine, so this is an all in one for us. The only 2 super minor changes I would make would be to add a fan sound (the ocean waves are as close as it gets to a fan sound) and change the time setup to the clock option (see picture 1). Currently, the Turns On time can be easily using a clock in the app, however, the Turns Off time has to then be calculated (picture 2), which seems more difficult than it needs to be. I would like to see the clock feature for both. All in all, I would recommend this to anyone with kids. It has truly been life changing and I am excited that it has so many capabilities to remain useful for years to come.UPDATE: After 1 year, we are still loving our Rest! I emailed Hatch with my recommendation to change the Turn Off time, they actually did it (I won't take full credit, but it is so awesome to see a company who actually listens to customers!) I have included a 3rd picture to show that the Turn Off now calculates the clock time for you rather than relying on sleepy parent math in the dark!
