With regard to your answer about both of you being called some form of mum, do you think there may ever be confusion when she calls out "mum" which one of you she wants?
Also, when she is in her teens and adult years, would you be happy and accepting if she was straight or would part of you hope she will also be a lesbian?
I have a gay friend who has been trying to help a lesbian couple he knows get pregnant. I learnt a fair bit from hearing about his experience. I don't think they have been successful in getting pregnant and staying pregnant yet, but it's interesting to hear from his point of view as the father to be. I know your situation is different because you used a donar who I assume you don't know.
