We stayed using this timer with our 20 month old son to start teaching him to play quietly on his blanket with his quiet toys. We actually weren't sure it was going to work at such a young age, but the large visual counter AND the clear "beep, beep" at the end actually got my son so excited the first time we used it, that he wanted to play quietly for another 30 seconds! He actually claps his hands and goes, "YAY!" when the alarm beeps. It's super cute. We've been training him on "blanket time" for a little over 2 months now, and have worked our way up to 3.5 mins of quiet! My husband says that it's one of his favorite times in the day, because the entire family participates by doing quiet things on our own blankets. It's sometimes the only time of quiet in the entire day! Lol. Thank you for providing such a fantastic tool for the littles in our lives
