How do you make your theme Child Theme-able? [duplicate]

Question

I'm sorry if this is an obvious question, but I've tried looking everywhere and can't seem to find an answer.

Are WordPress themes automatically Child Theme-able? Or is there a process to make a theme ready for Child Themes?

Answer 1

Few things have already been discussed here I would like to add more

In order to make your theme a good parent you also need to consider in following things:

• make your functions and classes pluggable ie, wrap your theme functions with function_exists wrapper so that they can be overridden in child pages.

  if ( ! function_exists( 'theme_entry_date' ) ) :
  function theme_entry_date(){...}
  endif;
  

• provide action and filter hooks generously
