I've told you before about the Sound Sleep Therapy System. This noise machine has been a big asset at my house over the last six months. Recently we have been able to try the travel size of this product, the Sound Sleep Nomad. I love this one too!
nomad has all the same features as the full sized version plus you can attach it to your MP3 player or computer to listen to your other devices as you travel. Recently we have been using the sound technology in D's room to help him sleep better through the coughing that is happening all too frequently at my house.
If you're looking for a great sleep aid that doubles as a speaker for everyday use you should be sure to check this one out. It's awesome!
