Baby-faced Alfie, who is 13 but looks more like eight, became a father four days ago when his girlfriend Chantelle Steadman gave birth to 7lb 3oz Maisie Roxanne.
He told how he and Chantelle, 15, decided against an abortion after discovering she was pregnant.
The shy lad, whose voice has not yet broken, said: "I thought it would be good to have a baby.
"I didn't think about how we would afford it. I don't really get pocket money. My dad sometimes gives me £10."
Alfie, who is just 4ft tall, added: "When my mum found out, I thought I was going to get in trouble. We wanted to have the baby but were worried how people would react.
"I didn't know what it would be like to be a dad. I will be good, though, and care for it."
Alfie's dad Dennis told how the lad does not really understand the enormity of his situation - but seemed desperate to be a devoted and responsible father.
Secret
He wanted to be the first to hold Maisie after the hospital birth. He tenderly kisses the baby and gives her a bottle.
And Dennis, 45, said: "He could have shrugged his shoulders and sat at home on his Playstation. But he has been at the hospital every day."
Maisie was conceived after Chantelle and Alfie - just 12 at the time - had a single night of unprotected sex.
They found out about the baby when Chantelle was 12 weeks pregnant.
But they kept it a secret until six weeks later when Chantelle's mum Penny, 38, became suspicious about her weight gain and confronted her.
