My friend and her wife had ivf to conceive their baby. My friend carried him but the egg they used was her wife's egg.I'm fairly sure she carried both, they were at the peak of their conning days just after the oldest one so I never really saw her during the pregnancy on the second boy so couldn't say if she was the biological mum or if Emma was as they dropped off the radar for a bit. Unfortunately the shame wasnt enough to keep her away altogether!
Think that was more to do with the ex having been in prison. They will both have parental responsibility for the children if they went down the proper ivf legal clinic route.I think greedy is the biological mum to them both as she took her ex to court for full custody and thought she was going to win
