Hi there, does anybody have a Cloud B Twilight Turtle? I've read the reviews and they say that the turtle has a sleep timer so it automatically turns off after 45 mins. I was wondering if its possible to have it permanently on or does it have to be on the sleep timer? My DS is 4 months old and I'm hoping the stars will help him get back to sleep when he wakes up during the night, but I don't want to have to go into his room each time to turn it on!!
