It's always good to take 1 step ahead in taking care of yourself, well for me it's better to consider what if rather than taking risk and blaming oneself later if something bad came up. the program is a big help i just hope that a 4 years old kid can really absorb such matters. Part of a safety precaution is this handy safety device that you'll always get protected 27/7. In a single pres of panic button a massive help would come. Safekidzone is best in this part.
