"We have finally decided on a name for the baby. She's called Dolly! It's actually the original name Alex and I liked in the very beginning and we've gone back to it," Houghton wrote on her column in new-magazine.co.uk.
The 28-year-old also shared her experience as a mother. "The baby seems to be sleeping a bit better than she was last week, so I'm hoping that was just a blip. She's sleeping for around five and a half hours at a time. I'm aiming for her to be going through the night by the time she's six weeks old," she wrote.
