Should i baptise my baby?

I have a 6 week old daughter and am debating whether or not to get her baptised catholic. I was baptised and so was her father but we do not belong to a church. We both believe in god but do not practic any religion. We are not married. Would this affect our daughter being able to be baptised? Do you have to belong to a church ? Do the godparents need to attend \ belong to church? Any advice or info would help. Thanks
