Mrs Radford was induced early, after going into hospital for a check up and Hallie was born weighing 7lb 15oz.
Mrs Radford wrote on her blog: "She’s so doted on by all her brothers and sisters and is settling in really well we are so in love with her."
After the announcement, followers of the family's website commented on her blog post with messages of congratulations, complementing the couple on their "gorgeous" baby and their choice of a "beautiful name for a beautiful girl".
Mrs Radford was induced early because her doctor noticed a reduction in the movements of her baby.
Mrs Radford has had a very tough couple of years. She suffered a miscarriage in September 2013. She became pregnant again in 2014, but the baby was born stillborn in July.
In September 2014, she wrote a moving blog post on her family website: "I am hoping that this pain does get easier because at the moment it is so painful. I have days when I’m ok then the grief hits me all over again."
The couple announced in December they were going to have another baby and since them Mrs Radford has been documenting her pregnancy journey on her blog.
She shared her HD4D scans of Hallie back in April and wrote about her excitement of bringing another baby into the world.
