As children grow older they need to learn to control their behaviour and learn to delay their own gratification. If children do not learn these skills they will not be able to fit in socially and behaviourally.
Failure to develop these skills may indicate a variety of problems. Be patient; work with others to identify or eliminate obvious causes, for example:
children who do not develop one sense properly often find learning difficult and they become frustrated
tired or hungry children function less well than well-fed, rested children
noisy or distracting environments may undermine self-control
