Want to work in NICU but have no acute experience

I graduated nursing school 2 years ago, and have spent my past 2 years working as a RN in a residential setting for emotionally disturbed youth. I have always wanted to work as a RN in the NICU or PICU. Of course I am no longer considered a new grad, so I cannot get an internship no matter how hard I try. I am wondering what to do, are there any hopsitals that allow teaching programs, maybe hire nurses with no acute experience but train them just as interns?
