our LO is 29 mo old. we have been using a toddler alarm clock for some time. we have the ok to wake clock if that matters. she knows that when the light turns green it is time to get up. our problem is enforcing it. she sleeps in a big girl bed and when she wakes up before the light goes off - like this morning for example - she leaves her room and comes to our room.

thoughts/tips on how to get her to stay in her room - quietly reading books, smile - before "the green light goes off"?
