My baby 2 ½ months and love it! I put him in the evening when I put it down and it's asleep ^^ Convenient Auto function that is recovering well on their way as soon as he makes a move. It is fixed to the ceiling projection whose image is very clear and pleasant music. As against the same music at least is a little strong. It did not wake him when he starts again but when you're in the room sides is heard and batteries wear out very quickly!
