Being called mum

[sizzledrizz]

I am often called this by those who work with my children: teachers, doctors, clinic staff etc.
I can understand if they are not familiar with my child and don't know dc's name, but it irks me when they could at least call me Mrs DC surname. I sometimes tell them my name, but they still insist on calling me mum.
The final nail has been that when my DC's father goes to collect them from school, a lot less than me, no teacher ever calls him 'dad'
Why is that?
Pisses me off

For all those saying it is to include the child, you must know lots of children don't call their mothers Mum or Mummy? My eldest called me Mamma until quite recently and when she was under about 2.5, I don't think she knew what people meant when they said "mummy" to her.

Staff at the nursery call me "Felix's mummy". It sounds slightly odd but is accurate. Once, I had forgotten something and one ran after me across the carpark shouting, "Felix's mummy, Felix's mummy, you forgot whateveritwas!"
