We could not live without this sound machine. I know that sounds dramatic, but it's ohhh so true!! We have an old Sharper Image one in Addie's room that you can no longer buy...so when Hayden was born I SCOURED the stores and online to find something comparable....enter Tranquil Moments White Noise Sound Machine. LOVE this machine! We have wood floors in our house, so sound travels and echos; and besides our house, as you'll read throughout this site, we travel a ton. I never wanted our kids to need a "perfect" place to take a nap or go to bed at night, however, we also need them to sleep. We have found that sound machines keep them from being woken up by each other, from noisy hotel neighbors, from us walking in and out of their rooms, from UPS deliveries, etc. In my mind I hope it's teaching them to NEED noise to sleep. (And I think it's working since we can run a lawn mower outside their windows at nap time! Goodness knows, we have A LOT of noise around here!)
