I have two custom objects, a parent and a child.  I have a requirement to be able to clone the child object record.  

• The Clone button is avialable when I edit the page layout, but is not visible on the live layout.
• I have searched for a permission I may have missed but am having no luck.  
• The child object records are not governed by record types.
• I do not need a custom clone button, I simply want to clone the record and edit where required.
