A sleep trainer works best when you set expectations—and make it easy for kids to meet them. In other words, if your kid wakes up at 5:30 a.m. on the dot, don’t torture them by setting the alarm to go green at 8 a.m.. Some parents give their kids a treat, like a sticker on a reward chart, if they manage to stay in their room until the green light comes on. Many sleep trainers also have a yellow light program option you can set for half an hour before wake-up. This means it’s not time to get out of bed, but it will be soon. Some parents find it’s helpful to give ideas of what a child can do during that time period. For example, they can play quietly with toys or look at a book, but they can’t leave their bedroom until the green light is on.
