Oma Sense monitors your little one's tummy movements through nap and bedtime so you can get some sleep knowing you'll be alerted if something is wrong. Using Levana's patented WakeUp Technology, if no movement is detected for 15 seconds, your baby is stimulated with vibrations, LEDs and audible alerts to encourage the return of regular movement. If movement does not resume 5 seconds after the first alert, an emergency alarm is initiated to let parents know their attention is needed. Oma Sense is cordless, battery powered and completely portable, so it can go with them to grandma's house. Featuring a patented one-handed clip, you'll never struggle to attach, adjust or remove the monitor without waking up your little one. For your convenience and baby's safety, Oma Sense was designed to be all-in-one, notifying you without the use of Wi-Fi, Bluetooth signals or an additional unit. Designed, Engineered and Made in Canada. Gender: unisex.
