Problems with a model

[eluser]Mat-Moo[/eluser]

Code:

class groups_model extends Model {
    //------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
    function groups_model()
    {
        // Call the Model constructor
        parent::Model();
        log_message('debug', 'groups_model created');
    }

&

class reminders_model extends Model {
    //------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
    function reminders_model()
    {
        // Call the Model constructor
        parent::Model();
        log_message('debug', 'reminders_model created');
    }

Both just extend base classes - I didn't realise you could have "Child objects though"? How does this happen, and how do you prevent it? And how can I check?
