Transgender parent

I watched a bit of it and was appalled at the way the father of the child paraded himself on the show! Ive no problem with his sexuality but to go about broadcasting it the way he did was so wrong. And to get the child to call him mummy was so wrong! As Ninthenanna suggested a pet name would be a good idea so as not to confuse the child any further.

We know a trans guy in the village who dressed as a woman at home for many years before coming out and undergoing the full surgical transition. The children were 12, 15 and 19 when this occurred and she has insisted on being called Mummy and her wife has remained as Mum. The three grandchildren call them each Granny followed by their name. The whole situation has caused a lot of problems for the kids, including getting beaten up and bullied at school. Unfortunately, her transition hasn't been as successful as some and she retains some very male characteristics-heavy set neck, muscled arms, receding hairline and quite a masculine face despite having had face refining surgery.

Crikey yes, I can see that would be a dilemma. Something like "daddy Mary" might work at home but when he starts nursery would cause a lot of problems.
I think I'd have to find a pet name for daddy that the child agreed with that wasn't gender specific
