Capitals for mum & dad?

When writing 'mum' & 'dad' in narration and dialogue, should they be capitalised? Not really sure if the 'name' rule applies.

 

I think it depends on how they are used.

If used as a name, "Over here, Dad," capitalise.

If used only for reference, "My dad is outside," don't capitalise.

 

it definitely does depend on how used... when used as a name, must have a capital... when not, it doesn't...

so kas' examples are right...

 

When being used as a noun, no capitalisation.
When being used as a proper noun, then it need capitalising.

 

Thanks everyone! I think my question has been answered the same by all.

 

YES. Always, always, always!

Just have a few things to add.

"Father, I need you for a minute."

"My father is outside. Please hold."

"Mum, do we have any more sugar?"

"My mum is inside... please let me go get her..."

Just make sure that you remember where you're putting it and you'll do fine.
