whether you like it or not.

And it takes a very patient parent to make them stop.

When it comes to TV and movies, however,

a director may actually want a baby to cry on command.

And this requires hiring someone

with a special set of skills.

That's Elaine Hall.

She's what's known in Hollywood as a baby wrangler.

Elaine Hall: A baby wrangler is a interpreter

between what the director wants a young child to do

in front of a camera.

Narrator: She's worked with infants and young children

on a variety of commercials, TV shows, and movies,

like "The Flintstones," "Grace Under Fire,"

and "Akeelah tnd the Bee."

First off, where do these crying babies come from?

Babies, just like adult actors,

come from casting calls,

but they're only legally allowed to work

for four hours a day on set,

so there's a simple trick used to extend their camera time.

Hall: Very often, when you see a TV show or a film,

twins are used to play one role.

Narrator: There's also a few other rules in place

when using young actors.

Hall: For every set that has a child,

there's a studio teacher on the set.

For infants, there must be a studio teacher and a nurse.

Narrator: For non-crying scenes,

working with babies and young children

involves making it fun for them.

Hall: Everything was made into a game.

I would put on the lens of the camera,

funny faces on the lens,

when they needed to make direct eye contact.

I would be behind the camera

on every scene, making them laugh.

Narrator: But for crying, it's a whole different story.

Elaine uses a special technique.

Hall: What I do to get babies to cry is,

I start to cry myself.

For example, I'll go, "Wahhhh!"

And the baby will start to cry.

When a baby, even an infant, hears another baby cry,

the infant or the baby will start to cry themselves.

This is an example of empathy.

It's pretty instantaneous.

Narrator: She used this technique in "Akeelah And The Bee."

In this scene, Akeelah's sister brings her baby

to the event, and it starts to cry.

And her technique has never failed, so far.

Hall: My success rate is 100 percent.

Narrator: She says she's heard of other baby wranglers

using questionable techniques like placing bad odors

in front of the child or making a loud noise.

But according to Elaine, these sorts of methods

may be harmful to the child, and should be avoided.

If the baby's face doesn't need to be shown on camera,

oftentimes, they'll use a doll instead.

Once it's crying, how do you get the baby to stop?

Hall: When I stop crying, and then I'll look at the baby,

and assure the baby that everything's safe,

I'm okay, she's okay,

then, very quickly, a baby will stop crying.

Narrator: She may also use rattles and bells

to help, if necessary.

Regardless of the scene, Elaine says it's important

that the baby spend time with the actor ahead of time.

Hall: I always have the actor and the baby

create relationship off camera,

so that it's not like you're just plopping a kid

into a stranger's lap.
