The Unborn 2009

Casey Beldon has nightmarish hallucinations of strange-looking dogs in the neighborhood and an evil child with bright blue eyes following her around. While babysitting Matty, her neighbor's son, she finds him showing his infant sibling its reflection in a mirror. Matty attacks Casey, smashing the mirror on her head, and tells her: "Jumby wants to be born now". She puts him to bed and leaves in shock.
