The Light Doesn't Sooth

So I bought this light at Target the package stated that it turned different shades of color (you can see it in the corner of this picture it is green and it is what he is staring at) and plays this soothing "womb" sound which is pretty much a thumping. Anyway I tried this device the other night thinking that he would put him to sleep at night. Well I put him to bed when he was almost asleep, turned on the light and sound and left the room... A few minutes later I hear this cooing coming from his room... I go in there and find him just mesmerised by this light that is changing colors. This light has completely energized him. So I pulled out the video recorder and taped him having a good ol' time... needless to say it took me another hour to calm him down, but he then went to sleep.
