Father: Amanda Knox taking things day by day

Amanda Knox returned to her hometown of Seattle on Tuesday, Oct. 4, 2011, after spending four years in an Italian jail. An Italian appeals court overturned Knox's conviction of sexually assaulting and brutally killing her British roommate, Meredith Kercher, in 2007. "I'm really overwhelmed right now," Knox told members of the media shortly after stepping off the plane. "I was looking down from the airplane and it seemed like everything wasn't real. "What's important for me to say is just Thank you to everyone who has believed in me, who has defended me, who has supported my family. My family is the most important thing to me right now and I just want to go and be with them. Thank you for being there for me."

Amanda Knox's father said his 24-year-old daughter has been taking things day by day since being released from an Italian prison.

During an interview on "Good Morning America," Curt Knox said Amanda needs to be reminded to speak in English.

"It has become really almost her first language since she's been in prison so long, but she seems to be moving to English," Curt Knox said

Amanda Knox returned to Seattle on Tuesday after spending four years in Italy and has been spending time with relatives.

Curt Knox says the family is concerned about her emotional well being.

"It's a big concern of mine if there's any traumatic circumstances that arise later on," he said.

The family has not yet decided on whether to seek counseling for her.

An Italian appeals court reversed Knox's conviction in the death of her roommate Meredith Kercher, ending her 26-year jail sentence.

One of the things Amanda Knox said she would do when she got out of prison was to lay in the grass.

"She has and it's been very nice to watch her do it," he said. "It's the little things that she hasn't had a chance to do in the last four years that really make it worthwhile and really kind of get her reconnected again."
