Actually my vet at least has the courtesy to call me "Tiddles's" mummy. The last time dd was in hospital the doctor introduced himself with his title and last name and said "you mum?". It is reductive, subordinating, ungrammatical, incorrect and wholly unacceptable. I simply shook his hand and said "I'm Mrs Roses, xx's mother".
One day an HCP will say "you mum" and I'll reply, "no I'm not, I actually have the full power of speech". And the fact that it's written in reports "dd's name and mum attended the appointment". They can't even be bothered to write dd's name and her mother attended the appointment.
My children call me mum, or mama, or ma. They are the only people in the world who are entitled to use that term. Nobody else is. It is incorrect for anybody other than my children to call me mum. I don't look up as a doctor arrives in the room and say "you doc". It would be extremely rude. I don't expect it to happen in reverse.
On a similar subject, I don't expect a doctor to use my first name either whilst expecting me to address him or her with a title. If they want to use my first name they can introduce themselves with their first name. If they want me to call them Dr Jones, Smith, Brown, then they can call me Mrs Roses. It isn't negotiable; it's an equality issue. Simple as. I am not their subordinate.
anyway I hope Tristan continues to do well and that his mother is now fully recovered from the upset of the first month of two.
