Babysitter / Babysitter


Babysitter is a reminder of changing disposable diapers for mothers. Long-time soaking in excrement will expose the baby to the risk of developing diaper rash, which can be prvented by Babysitter. The middle circle will change from blue to red when excrement is detected. In this way it simplifies the diaper checking procedure and help to keep babies’ small buttocks dry and clean.
