We have twin boys who were almost 3 when I bought the clock. They
would always get up at 6am, without fail, and come and wake us up.
We tried various ideas to try to encourage them to stay in their
room, but nothing worked. I bought the clock on a whim because it
was on sale.
Best. Decision. Ever.
We set the clock to turn green at 6:15am the first morning, then
6:30, 6:45 and finally after about a week or so, 7am which was our
final goal. The boys often wake up before 7am but will stay in
their room, reading, playing or chattering to each other. Then they
come running excitedly into our room at 7:01am exclaiming, "The
clock is green!". They love pushing the button and having the clock
tell them the time, but they don't do it so often as to be
annoying.
The best test was this past weekend when the time fell back an
hour. The boys still stayed happily in their room until 7am...and
we got an extra hour of sleep. Yay!
