It's a magic lamp ... Just take it in hand and your dearest wishes come true! The rabbit (he lamp engineering) learn very quickly to your children to respect the hours of sunrise and sunset. You have to see, once they have understood the principle, with what pleasure they shout "Mamaaaaan, lapiiiiin" when the alarm gives them the green light to get up. Well, it goes fast to them, eventually they get up quietly at the scheduled time. This is the second that I buy because the first is still used for my big and it took me one for my second who just turned 2 years!
