How did Rhea trick Cronus?

Answer 1

rhea wrapped a bunch of rocks in a cloth and gave it to Cronus who swallowed it. Gaia, Cronus' mother had foretold that one of his children would overthrow him, to prevent that from happening, he swallowed all his children.

In order to save her youngest child, Zeus, from the fate of her other children (being swallowed by Cronus), Rhea, with help from Gaia, hid Zeus in a cave after she gave birth to him and presented to Cronus a stone wrapped in swaddling clothes (basically, it was a rock dressed as an infant would be). Cronus, believing it to be Zeus, promptly swallowed the rock.
