We recommend that the Sensor Pad is suitable up to approx. 2 years old.
As baby gets older their sleep patterns change and the rise & fall of the upper chest area becomes less rapid compared to a baby.
As a result you may experience false alarms.
We also know that a lot of parents stop using the Sensor Pad around this age as baby is climbing out of the cot/bed and causing numerous false alarms.
However, you can at this time deactivate the movement function on the Parent Unit (where included) and continue to use the monitor but as a Sound (and Video where included) monitor.
