They're not demonic babies. They're "zombie babies". In case you still don't believe me:
WARNING: Do not click unless you are sure you want to see this. Once you've seen a zombie baby, you will never remember a time in your life when you hadn't seen a zombie baby. And if your husband goes out of town for work, any little creak in your house at 2 a.m. will obviously be a group of zombie babies breaking into your house to eat your eyeballs.
