I hate mom/mum (and nor really into mummy either but young kids needs that) so they get to choose -my first name or mummy/mommy
. I will answer to mom. Sometimes. But it had better be good.
Beest prefers Dad or Daddy -the boys call him Dad and the girl Daddy. All teenagers. They've always used my first name when calling up into crowds because 75% of the people up there are called Mom. It probably changes when they became teenagers/went to high school -their elementary education was all in one school so no Middle School/Junior High experiences to force the change
