Little League. Cat & Mouse

[Bandit]

History and background is in softball. Have son starting 9 and 10 year old age group baseball this year. Have expierenced the cat & mouse game of runners at first base this past week-end to try and draw a throw. Softball has the look-back/circle rule to prevent this bs. What is the Little League rule on this. Where in the rule book is the direct ruling on what the responspbility of the runner/base commitment vs ball to pitcher? Want to teach the son the proper ruling and action. He will have considerable time as catcher this summer. Thanks
