Corrected entry: When Kathy goes to her daughter's window to shut it, the red eyes that appear outside during the dramatic horror effects are too wide apart to be a small child's eyes.

Correction: What Kathy saw in the window was Jody the pig. (I know it's stupid).
Correction: It's the demonic pig-like entity outside (you even lightly hear the sound of a boar snorting), not a little girl's ghost. Hence, the eyes are further apart. But even beyond that, given it's a supernatural, potentially demonic being, real-world logic (such as having a consistent head shape) doesn't necessarily apply anyway.
