My son has had from birth and became interested to 2-3 months. He loves teddy that turn! Today it has almost seven months and is still a fan! He groans when they stop! The remote control is convenient because it allows remotely turn on without baby sees us. A little disappointed by the starry projections: they barely see. You really have a black suit. Too bad also that the mobile turns only 5 minutes. It's too short. We are forced to go on again 3-4 times before a baby to sleep. The music is nice and the volume not too loud. The mobile u motor is very quiet by cons. When you put the mobile on without music it's still bpc noise.
