TTC Thursday Who's the Mummy?

As I have mentioned before Paul and I will start our fertility journey once we are married but that doesn't mean we don't think about babies and our future family. I go on a few forums and there is a big debate around egg sharing and who the biological mother of the child is. It all comes down to your school of thought on the meaning if the word biological. If you think biological is being related by blood then the egg recipient is the mother as it is her body and blood that's takes the egg from cells to a living baby. If you believe biological means related by genetics then the egg donor is the biological mother of the child aS her egg carries all the genes or blue print to create the baby. What are your thoughts?
