THE UK's youngest mum has spoken about her mixed feelings following the birth of her second baby girl.

Tressa Middleton, from Bathgate, West Lothian, made headlines in 2006  when she gave birth when she was just 12 years old.

Now Tressa, who is now 24, said she hopes her baby Arihanna can meet her older sister when she grows up.

In an interview with the Sunday Mail newspaper, she said: “I felt pure joy the moment Arihanna was born.

“There were times I thought I’d never have another baby, like it wasn’t meant to be.

“But I also feel so guilty, because Arihanna is with me and my older daughter is not. It breaks my heart that Arihanna will grow up without knowing her big sister.”

Tressa welcomed her daughter with partner Darren Young, 31, in October.

She added: “Arihanna will always know she has a big sister.

"I talk to her about it now, even though she can’t understand. She’ll never be a secret.

“I really hope that one day they can meet. It would mean the world to me.”
