Remie is the couple's fourth child who came after a series of fertility struggles for the pair.
'She offered to leave me after our third attempt at IVF failed. I just told her I loved her and I would never leave her, even if I would never be a dad,' Thurston told the Daily Telegraph.
'My heart broke for her,' Thurston added.
'There is no way we were expecting this. All three of my girls were born through IVF and this happened naturally,' he said.
