A THIRTEEN-year-old boy has become a father with his 15-year-old girlfriend but isn't sure how they will cope financially, because he doesn't know what the word means. British boy-dad Alfie Patten yesterday admitted he does not know how much nappies cost but said: I think its a lot. 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 Maisie Roxanne, The Sun reports. He told how he and Chantelle, 15, decided against an abortion after discovering she was pregnant. When asked how he is going to cope financially, Alfie replied, bemused, "What's financially?" The shy boy, whose voice has not yet broken, said: I thought it would be good to have a baby. I didnt think about how we would afford it. I dont really get pocket money. 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 didnt know what it would be like to be a dad. I will be good, though, and care for it. His father Dennis Patten, 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. See the baby-faced dad and see video of him talking about the child at The Sun.
