How to teach young toddlers to use scissors

Some parent asked me how to train toddler to use scissors, because most of childcare center or kinder garden will only teach on how to use scissors at 4 years above.

I told them, practise using the scissors with their young toddler, do it by holding their hand in your hand, put your fingers into the scissors with your toddler fingers, speak out rythm such as open, close, open, close ...etc to make them know to use scissors must have rythm
