My mum is having a baby. I'm happy for mum. I hope my mum has a baby girl.
There are three instances of the word mum in the example. I thought the first and third did not need capital letters as they as simple nouns, used in the same way as the word 'mother'. I corrected the second sentence to read: 'I'm happy for Mum' because it's a pronoun.
I was told that all instances of the word needed to be capitalized because 'mum' is abbreviated. What do you think?
"My mum is having a baby. I'm happy for mum. I hope my mum has a baby girl.
You need not capitalize 'mum' when you write 'my mum'.
However, if you write 'Mum' without 'my', it is correct to capitalize 'mum'.

I agree with Yoong Liat.
The second use of 'Mum' is capitalized because here you are using the word as her proper name.
Capitalization is not related to whether or not a word is abbreviated. You'd also say 'I'm happy for Mother'.
The word 'mum' is not a pronoun.
