I just told Phebie that her Aunty Makaylah has a baby in her tummy and she asked if she'll be its Aunty too, I told her no that she'll be its mummy and Adam will be the daddy and she looked at me like I was crazy because her name is aunty maka not mummy
My friend's little one gets annoyed if you call his grand parents anything other than Granda and Gramma. My friend called them Mum and Dad once and he stood in front of her, stamped his feet and said "Not your Mummy and Daddy!!! My Gramma and Granda!"
