It’s so easy, without a word, to entice children into a game. While Mum or Dad or Nana or Granddad (or someone else) isn’t watching, give a child ‘the eye’ and take one step in the direction of the unsuspecting quarry. Put a finger to your lips, crouch slightly, and without a sound take a step closer.
You remember, the idea is to creep up on the ‘victim’ and get as close as you can before they see you. One of the things I love about playing with children is the reawakening of the child within. It’s good for you.
