EDITOR’S NOTE: Redbox machines are full of terrible B-movies. You know it. I know it. Each week, a brave Daily staffer will take the plunge and watch one of them so you don’t have to.

Given my penchant for watching terrible horror movies, and my luck of finding not one but two flicks featuring murderous infants inside my local Redbox, I had no choice but to make this a double feature.

Part one, “It’s Alive,” is a remake of a 1974 film. It takes the mutant route, citing “natural miscarriage” pills from the Internet as the cause for baby’s thirst for blood.

Lenore (Bijou Phillips) is a college student who drops out to raise her baby with boyfriend Frank (James Murray). When the baby grows at an alarming rate, she must deliver early by c-section. Conveniently, Mommy is sedated for the procedure, so she doesn’t witness the bloodbath created by her newborn son.

After some police questioning, she is allowed to go home — who would suspect a baby of murdering a room of medical staff?

But home is where the trouble starts. Sure, Demon Baby grows crazy fast and sports teeth, but Lenore writes this off as being “special.”

So special, in fact, that he is soon able to leave the house and hunt wild animals. Lenore is initially grossed out, but she learns to accept and hide her precious child’s dirty work, even when he starts murdering relatives.

Finally it becomes obvious that something is terribly wrong, but it’s too late. Somehow, the house is on fire. Frank flees, but Lenore refuses to join him. She takes the baby into the flaming house and they die together in a blaze of glory.

Compared to part two of this double feature, “It’s Alive” is pretty straightforward. “Grace” offers up a lot more intrigue.

Although she miscarries in a car crash (which also kills her husband), Mommy Madeline’s (Jordan Ladd) crazed grief and baby fever leads her to decide to carry to term anyway.

This decision is supported by her midwife, former teacher (who reportedly “revolutionized women’s studies,” whatever that means) and ex-flame Patricia (Samantha Ferris).

When Madeline delivers her stillborn baby, it’s pretty gruesome. (My notes say, “OH MY GOD, SO MUCH BLOOD.”) But she wills it back to life with ... love? Hope? Women’s studies? The dead baby becomes Grace.

The scariest part about this movie isn’t the bloodthirsty baby, if you can believe it. Sure, flies are oddly attracted to her, and she drinks Mommy’s blood instead of milk (“She’s special. She needs special food,” the rationalization goes), but she’s more like a catalyst for the real horror show of the other characters.

Like Madeline’s mother-in-law, Vivian (Gabrielle Rose). Viv deals with her grief over her son’s death by developing an obsession with breastfeeding. I don’t have to tell you it’s creepy. Especially when she actually begins to lactate. This fuels her mission to get Grace and raise her.

But to do that, Madeline must be proven unfit. So Vivian sends her doctor over to check the sitch. After he deems her badly anemic (duh), the doctor is murdered by Madeline to protect herself and feed Grace with his blood.

She also kills Vivian, who shows up shortly after, inexplicably carrying a hammer.

In the end, all is ... well? Patricia, who has been lurking outside Madeline’s house since Grace’s birth, has bought an RV. The two dye their hair, to hideous effect, and hit the road. Patricia is optimistic: “We keep your blood levels up, and we can do this.”

But she’s in for a surprise. “She needs more now,” Madeline says. “She’s teething.”

Cut to torn-up bloody chest, and roll credits. Wow.

So what lessons do “It’s Alive” and “Grace” teach us? Don’t order shady pills online — they’ll make your baby a mutant? Veganism is the answer? Women are so dead-set on being mothers that they’ll stop at nothing to protect their offspring, no matter how evil?

We may never know, but in the meantime, take heed of “special” babies. They may just eat you.
