Fisher Price has a baby soother that works well to help lull your baby or little one to sleep. It is called the Fisher Price Rainforest Waterfall Soother and hooks on to the side of your child's crib. this soother has multiple settings for sound including light music, waterfall sounds or lullaby melodies. The fish swims around on the bottom while a monkey and frog playfully poke their heads around the leaves above the water. The system also can run with or without a light display to help stimulate or calm your child's senses down for the night. the run time on the battery is great, up to almost 20 minuets straight through on one button push. Our son found this product to be very good especially on nights where he just couldn't get his eyes closed and rest to quiet time, the soothing sounds helped alot for him. Also the animals would give him something to look at in the early morning once he figured out house to push the easy to use buttons on the front of the toy. He loves the songs and sounds to slowly let him wake up. The system runs on 4 C batteries and is great for a new or additional member of the family or as a gift for someone having a baby who might like something out of the ordinary that will help on some restlessness nights!
