This clock is great! My son is forever waking up at 5am and waking everyone else in the house too.  Within a week he waking up and knows it is too early to get up and falls back to sleep!  We don't use the buzzer and it is great that you can turn it off.  I can see it will come in handy when he is little older.  I love an item that will grow with him.
