Baby Smile's baby monitor. Includes instruction manual. Used for 3 months starting July 2024. As a measure against SIDS, it eased my anxiety about not being able to sleep, worrying about whether my baby was breathing at night. I confirmed that it works without any problems. The alarm also sounds. Batteries are not included, and it will be shipped with the box. I was able to use it with peace of mind because it was also used at a famous maternity hospital and postpartum care center. There is some slight paint chipping, but I think it's not noticeable. Please check the photos.
