Millie Radford gave birth to her first child last week.
On September 10 at 7:05pm, the 19-year-old welcomed her daughter Ophelia into the world.
The newborn weighed 7lbs and 12oz and is the latest addition to Britain’s biggest family – the Radfords.
Mum-of-22 Sue filmed the aftermath of her daughter’s birth for a YouTube video.
In the clip, she said: “Millie managed on gas and air. She came in at six centimeters, and you did brilliantly didn’t you.
“I can’t believe you came in at six centimetres, and she was born five hours later.”
Sue was very proud of her daughter – especially as Millie’s birth wasn’t easy.
The Radford family matriarch said the baby “was not in a good position to come out”.
Millie added: “I think that’s why it took so long.”
After a long time in labour, the teenager had to have surgery.
Sue explained: “After Millie had had Ophelia, she had to go to theatre because she’d got a secondary degree tear.”
Sue continued: “So she was in theatre for a few hours and I had Ophelia, bless her.
“Millie was in theatre for I think, two hours. And she’s doing really really well.
“But I don’t think Millie will be allowed home until later on tonight, because while she was in theatre she spiked a temperature and Ophelia had pooed inside Millie just before she was born.
“So they need to make sure neither of them have an infection going on, so they need to monitor them for 24 hours.”
Thankfully, Millie seems to be doing well now.
Her huge family has gathered around to meet baby Ophelia – and everyone seems smitten with her already.
On Instagram, mum Sue gushed: “Welcome to the family beautiful Ophelia.
“I can’t even put into words how incredibly proud I am of @millieeradfordd you did AMAZING bringing this beautiful blessing into the world.
“We love you both so much.”
Sophie Radford commented: “Welcome to our family Ophelia. You are perfect in every way.
“I can’t explain how proud I am of @millieeradfordd you have created a very, very beautiful little human who I can call my niece I love you both so much.”
Another of Millie’s sisters, Chloe, gushed: “I’M AN AUNTIE AGAIN!!!
“Another beautiful blessing to the family, Ophelia Radford. I love her so much.”
And the teen’s brother Luke added: “Welcome to the mad house baby O.”
