In your experience are there children who just don’t have the temperament to meditate? My child can’t sit still...
No all children can meditate; you can choose a meditation that is more suitable for your child’s temperament. For a child that cannot sit still very long, engage them in a guided meditation where their mind is being brought under control and focused. We can also find some active meditation techniques like playing in nature or music and dance; anything that can be done with mindfulness of the present moment and focus is meditation for a child.
