We're ecstatic but...How do we tell my parents?

Tell her like you told us. But more so like this.."mom and dad you know how ______ and I feel about one another and that we plan on getting married. Well we recently found out that we are going to have a baby soon. Now we know that you may think we are moving to fast but we are both responsible and we have deiced to keep the baby. I hope you all can be happy for us and support us with any questions or help we may need. "
