"I want to be there financially, mentally and physically in the baby's life. I'm going to do whatever is possible to take care of him.
"I would like to try to be his mentor, to be his role model, to be his father in every aspect of his life. I want the baby to know me both as a father and also as a person that's in his life all the time. Nathan is mine and I'm going to be the best father that I can."
"If he really wants to provide for the baby, he should get a job! But I don't think he's willing to give up the party lifestyle. I think he's a selfish little twit."
"I think that he's incredibly selfish and immature and I don't think he's willing to sacrifice himself to take care of another life," she says.
"You do understand how important it is for a child to know his father?" Dr. Phil asks Alexandra. "You're not resistant to that in any way, right?"
"No, not at all," Alex says. But two days earlier, in a heated phone call, Alexandra told the father that he couldn't stop by the house to visit Nathan.
"You're not a good person," she tells him. "I'm the one who was pregnant for nine months ... I'm the one who pushed the thing out."
Erin listens to the conversation and then commends Alexandra on staying strong. "Good job," she tells her daughter and then asks, "Who's most important now?"
"Nathan," Alexandra answers.
Erin says: "He was threatening Alexandra late in the pregnancy telling her that she wan't going to be a good mother and that he was going to take the baby away.
"But I certainly can't imagine him waking up three times a night to give the baby a bottle. There is no way that I want Nathan to end up like his biological father."
