There are several benefits to using baby sleep tech. Sound machines and white noise machines produce constant sounds to mask any ambient noises that might disturb a sleeping baby. Baby monitors enable parents to check in on and listen to their baby without entering the child's room. Sleep trackers monitor the baby's breathing, movements, and sleep cycles to give parents an insight into their child's sleep patterns. Smart cribs, meanwhile, integrate several technologies to create an optimal sleep environment.
