This weekend you got to meet your step-grandma. We shall call her 'Aunty T'.
Or 'Grandma T' (the suggestion of your 11 year old sister)
Or GT (suggested by your 13 year old sister)
or G-Tiz (currently tentatively used by your big brother)
There is a current (and very important) debate going on between your brother and your sisters about which name is most fitting, and I think that it is so particularly difficult because it is hard to find a name that conveys how they feel about their step-Grandma, but doesn't offend anybody or denote the roll of the other Grandma's in their life.
Up until now, your step-grandma has been called Aunty. But your birth seems to have sparked this debate, with your big sister declaring that 'she isn't our Aunty, she has always been like our Grandma since we were born"
"... plus it is kinda weird having our Aunty be married to our Grandad"
You can't argue with that logic.
I am sure that we are not the first family who has more steps, halves and other combinations than you can poke a stick at. Mummy and Daddy both have step brothers and sisters, and half brothers and sisters. Which means that you have a step-Grandma and a step-Grandad too.
Regardless of the internal politics of adults and society, to your brother and sisters, your 'steps' and 'halves' are simply no different or any less important than any other people in your family.
They are people who they have known all of their lives (or as long as they can remember).
People who they have laughed and cried with.
People who have held their little hands as toddlers
People who have taught them how to thread bait on to a fishing rod correctly (step-Grandad Anthony... the jury is currently out on a fitting name for him also!)
People who have fed them too much ice-cream when Mummy said "no"
People who their Aunties call 'Mum" and their cousins call "Grandma"
People who have been a fixture of their lives for as long as they can remember
And regardless of the labels put on them by the adults and society around them, to you and your brother and sisters, they are simply your family
