hi and welcome,
I am just dumbfounded as to why your partner would be called aunt. You are both legally going to be bubs parents.
I am the tummy mummy and i will be called mummy and my dp will be called mumma.
with regards to schooling on fathers day, poppy will go in. (My dp's older brother has asked why it cant be uncle's day lol) and most schools are fine with adapting things as there are alot of children out there that dont have fathers.
I think that it would be very confusing for your child if she calls her mum "aunt" it just isnt right. This is only my opinion so hopefully I havnt offened you
I think you might you to take the bull by the horns when it comes to this. Be straight and say no we are both females and both parents. We will both be mum!
As your bubba grows up they will know that they are special to have 2 luvin mums instead of 1.
We have had alot of comments also but nothing to the extent of being called aunty.
For us there was no doubt on what we would be called and how we would handle school.
Motherhood is a process that you both should experience and I know for a fact that my partner would not feel involved as a parent if she was to be called "aunty".

For our next bubba we will be using my partners egg with our same unknown donor and I will be carrying again. Due to medical reasons. My partner loves all the attention she gets and loves talking to my growing belly saying "mumma loves you very much" and "mumma cant wait to meet you"
Dont back down as your DP deserves to feel as much as a mother as anyone.

Goodluck hun and I hope you get your BFP soon.

You go and straighten out your DP's mum quick smart.


Take care and I am here if you wanna chat
