We use one for Bailey and he loves it, I think it was from Big W for about $15 - it projects teddy bears with stars and moons on the ceiling and has a few tunes - we play the "Lullaby and Goodnight" tune and by the time it finishes (you can choose 5 or 10 mins) he is usually always asleep, its great when he awakens as we generally play it and he resettles himself. If I am rocking him to sleep in my arms and hum the same tune he drifts off as well. I would definately recommend them
