Rosemary's Baby
It happens to every girl: you meet a guy, get married, and next thing you know, he's renting out your woman parts to the Devil. An epidural will be the least of your concerns once you realize you're giving birth to demon spawn. Worse yet, rumors of a Michael Bay-produced remake briefly surfaced in 2008. Just imagine -- all the excruciating pain of Satanic labor, plus explosions.

The Fly/The Fly II
Congrats! Once the contractions and Lamaze are over, it's all Beanie Babies and soccer games from here on out -- unless, of course, you're the proud mother of a bouncing baby larvae. The moral: use contraception, especially during sex with a dude who looks like he might be part fly. The birth, as pictured above, is a dream sequence in the first film. The actual birth opens the sequel, which undergoes a metamorphosis from squishy over-sized maggot into Eric Stoltz.
Dawn of the Dead (2009)
You might be ready to deal with the occasional diaper rash, but no amount of Dr. Spock will prepare you for an undead child. In one early cut of the Dawn of the Dead remake, the newborn killed its own mom in this scene. Kids today, am I right? Check out director Peter Jackson's (yes, that Peter Jackson) splatstick classic Braindead for more zom-baby hijinks:
