One of my friends has always called her mum by her first name, not 'mum'. And her brother's DCs call him and his wife by their first names too.
I think this is a real shame. Whenever I'm with them and I see the little boy tugging on his dad's sleeve and saying 'Jeff! Jeff!'* to get his dad's attention, I just feel there's something wrong with that picture.
Not sure how you can be a parent and not want to hear your children call you 'mum' or 'dad'.
What do other people think about this?
*not his real name, obviously.
