We ordered the family pack of calm carrys as we are a nuerodivergant household and both our Children have always struggled to wind down at bedtime, and then have had difficulty sleeping through the night. Within days of using the devices, our Children were falling asleep within minutes and are sleeping through the night. On the rare instance that they do wake up, the device is easy for them to operate alone and they turn it back on to help them fall back to sleep. These devices have changed our lives! After years of trying sleep training, bedtime routines and nothing working, we didn't know if they would ever sleep and we were always exhausted. We are so grateful to have found something that actually works as the Doctors had started recommending medication for our 6 year old and that's something we wanted to avoid. Would highly recommend.
