For the First Time, They Slept Side by Side: The Day Erin and Abby Delaney Became Two. Hyn
For ten months, Erin and Abby Delaney knew the world in a way no one else ever would.
They entered life together, not just as twins, but as two souls joined at the head, sharing more than birthdays, more than a bond, more than a beginning.
They shared a physical connection so rare that even seasoned surgeons describe it with reverence.
A condition called craniopagus.
A life defined by closeness no human plans for and no parent can ever fully imagine.
Until one historic day in June, the sisters had never faced each other.
They had never rolled apart.
They had never known what it felt like to rest without the presence of the other.

And then, after eleven hours in an operating room filled with quiet intensity, everything changed.
For Heather and Riley Delaney of North Carolina, the journey began long before birth.
At just eleven weeks into Heather’s pregnancy, doctors delivered news that would instantly reshape their future.
They were expecting twins.
Conjoined twins.
The words landed heavy, unfamiliar, and terrifying.
Questions followed immediately.
Would the babies survive?
Would they suffer?
Would separation even be possible?
By nineteen weeks, Heather and Riley were traveling regularly to Philadelphia, where specialists at the Children’s Hospital of Philadelphia began monitoring the pregnancy closely.
Each visit brought new information, new risks, and new hope.
By twenty-six weeks, Heather remained in Philadelphia full-time.
The waiting had become too important to do anywhere else.
On July 24, 2016, Erin and Abby were born by C-section.
Ten weeks premature.
Each weighed just over two pounds.
Tiny.
Fragile.
And joined at the head.

From the moment they arrived, the girls were surrounded by machines, medical teams, and watchful eyes.
But they were also surrounded by love.
They were named.
Held.
Spoken to.
Not as a medical case.
But as daughters.
Craniopagus twins are extraordinarily rare.
Most conjoined twins are joined at the chest, abdomen, or pelvis.
Being joined at the head presents one of the most complex challenges in medicine.
Shared blood vessels.
Shared membranes.
Two brains working independently, yet connected by structures never meant to be divided.
From the beginning, doctors knew separation would not be simple.
Or quick.

It would require months of preparation.
Careful mapping.
Multiple specialties working as one.
And absolute precision.
While Erin and Abby grew stronger, they underwent therapy that most babies never experience.
Physical therapy.
Occupational therapy.
Speech therapy before speech.
Movement training before movement was fully possible.
All while still joined.
Doctors studied scans.
Built models.
Planned every step long before the first incision would ever be made.
There would be no room for improvisation.
No margin for error.
On June 6, 2017, the day arrived.
Inside the operating room at CHOP, more than thirty medical professionals took their places.
Neurosurgeons.
Plastic and reconstructive surgeons.
Anesthesiologists.
Nurses.
Each person knew their role.
Each movement mattered.

The surgery was led by Dr. Gregory Heuer, a neurosurgeon, and Dr. Jesse Taylor, a plastic surgeon.
Both understood the weight of the moment.
This was not just a procedure.
It was a transformation of two lives.
The operation would last eleven hours.
Eleven hours of meticulous separation.
First, the shared blood vessels.
Then the dura, the protective membrane around the brain.
Then the most delicate part of all.
The sagittal sinus.
A critical vein that drains blood from the brain.
Separating it required precision beyond measure.
At a certain point, the medical team split in two.
One group for Erin.
One group for Abby.
Green tape marked one baby.
Purple tape marked the other.
Two patients.
Two heart rates.
Two futures unfolding in parallel for the first time.
Throughout the surgery, anesthesiologists tracked every change.
Every breath.

Every fluctuation in blood pressure.
Every moment of stability.
When the final separation was complete, reconstruction began.
Skull.
Scalp.
Skin carefully shaped and closed.
The girls were no longer physically connected.
But the work was far from over.
After surgery, Erin and Abby were taken to the Pediatric Intensive Care Unit.
Monitors surrounded them.
Doctors watched closely.
Waiting.
Not celebrating yet.
Because recovery would be long.
And uncertain.
Separation surgery is only the beginning.
Healing takes time.
The brain needs rest.
The body needs to adjust.
Nutritionists and developmental pediatricians joined the care team.
Focused on helping the girls thrive as individuals.
This surgery marked the twenty-third time CHOP surgeons had separated conjoined twins.
But it was the first time they had separated twins joined at the head.

A milestone not just for the hospital.
But for medicine.
For the first time in their lives, Erin and Abby could lie side by side.
Not face to face.
Not pressed together.
But apart.
Each in her own bed.
That image alone carried years of effort.
And unimaginable emotion.
For Heather and Riley, the moment felt surreal.
They had imagined it for months.
But nothing prepares you for seeing your children as two distinct bodies for the first time.
Two separate spaces.
Two different ways of breathing.
Moving.
Sleeping.
“When we go home, it’s going to be a big party,” Heather said afterward.
A welcome home.
A baby shower.
A first birthday.

Celebrations that once felt uncertain now felt possible.
The girls will likely need additional surgeries in the future.
Their journey is not over.
But it has crossed a threshold many once feared they might never reach.
This story is not just about surgical success.
It is about patience.
About trust between families and medicine.
About planning measured in months and millimeters.
It is about two babies who never knew separation.
And then learned it gently.
Safely.
Carefully.
It is about parents who made impossible choices.
And waited.

And believed.
And it is about a moment so simple, yet so profound.
Two sisters sleeping side by side.
Not because they must.
But because they can.
For Erin and Abby Delaney, the world has finally widened.
They will learn who they are individually.

How they move.
How they play.
How they grow.
They will always share a bond deeper than most siblings.
A beginning no one else can claim.
But now, they also have space.
Space to become themselves.
And in that space, a new story begins.

Half a Heart, a Whole Fight: Living With HRHS From the First Breath

Ania entered the world the way every child does.
Small. Warm. Held carefully in her parents’ arms, already loved more than words could ever explain.
But almost immediately, doctors began to speak in a different tone.
Quiet. Careful. Heavy.
Ania was born with Hypoplastic Right Heart Syndrome, known as HRHS.
A congenital heart defect so rare and severe that it changes the meaning of the word “normal” from the very first breath.

HRHS means that the right side of the heart never fully developed.
The chambers that should pump blood to the lungs are too small or nonfunctional.
In simple terms, Ania was born with only half of a working heart.
For most people, the heart is something you never think about.
It beats without asking permission, without reminding you how essential it is.
For a child with HRHS, the heart becomes the center of everything.
Every breath.
Every cry.
Every future plan.
When parents hear this diagnosis, the world collapses inward.
Questions come faster than answers.
How can something so tiny be so broken?
How can a baby survive with half a heart?
What kind of life waits on the other side of this diagnosis?
HRHS is not a condition that can be “fixed.”
There is no surgery that creates a new heart chamber.
There is no medication that makes the right side grow.
Instead, survival depends on a series of complex heart surgeries designed to reroute blood flow so the single functioning ventricle can do the work of two.
From the very beginning, Ania’s life became a race against time.
Newborns with HRHS cannot simply go home and grow stronger.
Their circulatory system is unstable.
Without intervention, oxygen-rich and oxygen-poor blood mix dangerously, starving the body of what it needs.
Ania was taken not to a nursery, but to intensive care.
Monitors surrounded her.
Tubes carried oxygen.
Machines became her lifeline.
Her parents learned a new language overnight.
Saturation levels.
Pressure readings.
Alarms that could change a moment from calm to terror in seconds.
Waiting became their full-time existence.
Waiting for weight gain.
Waiting for stability.
Waiting for the moment surgeons said she was strong enough to survive the first operation.
Children born with HRHS typically undergo three major open-heart surgeries.
Each one carries significant risk.
Each one is necessary for survival.

The first surgery is usually performed in the first weeks of life.
It stabilizes blood flow and prevents immediate heart failure.
For parents, those hours in the operating room are unbearable.
They know their child is in the hands of experts.
But they also know that no expertise can guarantee an outcome.
A heart is not a bone.
It cannot be replaced easily.
It cannot rest.
When Ania went into surgery, time stopped for her family.
Every sound in the waiting room felt too loud.
Every silence felt too long.
When she came out alive, it felt like a miracle.
But miracles with HRHS are never the end of the story.
The second surgery comes months later.
It further redirects blood flow, easing the burden on the single ventricle.
By this time, parents have become experts without diplomas.
They recognize subtle signs of distress.
Faster breathing.
Bluish lips.
Hands that turn cold too quickly.
They learn that their child’s body is always working harder than it should.
That fatigue is not laziness.
That shortness of breath is not weakness.
Between surgeries, life is fragile.
A simple infection can become dangerous.
A fever can threaten everything.
Parents learn to live in constant vigilance.
They celebrate small victories others take for granted.
A good night’s sleep.
A steady appetite.
A walk without turning blue.
Ania’s second surgery was another test of endurance.
Another day of fear.
Another recovery marked by pain, patience, and hope.
But even after two successful operations, HRHS does not loosen its grip.
The third surgery is the most complex.
It is often performed years later, when the child’s body has grown enough to endure it.
This procedure places enormous strain on the heart.
It requires precision, experience, and perfect timing.
For children with HRHS, this surgery determines long-term survival.
It is not optional.
It is not cosmetic.
Without it, the heart slowly fails.
Ania’s parents began to notice signs no one else could see.
She tired faster.
Her breathing became shallow with exertion.
Her fingertips sometimes turned blue.

To outsiders, she looked fine.
To her parents, her heart was whispering that it was struggling.
HRHS does not always announce danger loudly.
Sometimes it shows itself in subtle ways that only those closest can recognize.
Doctors confirmed what her parents already feared.
Her heart was reaching its limits.
The third surgery could not wait.
In many countries, this operation is not fully covered or requires access to highly specialized surgeons.
The difference between a good outcome and a devastating one can depend on experience measured in thousands of cases.
For families, this creates another unbearable layer of stress.
The fear of the surgery itself.
And the fear of not being able to afford it.
Because heart disease does not pause for fundraising.
It does not wait for paperwork.
It does not care about bank accounts.
HRHS is a lifelong condition.
Even after all three surgeries, the heart remains fragile.
Children often face complications later in life.
Arrhythmias.
Heart failure.
Liver issues caused by altered blood flow.
Some will need heart transplants as adults.
Some will live shorter lives.
And yet, children like Ania fight with a strength that defies logic.
They smile in hospital beds.
They learn to walk with wires attached.
They laugh between procedures.
Their hearts may be incomplete, but their will is not.
Living with HRHS means living with uncertainty.
No parent is ever fully relaxed.
No milestone is ever taken for granted.
But it also creates a depth of love few people ever experience.
Every heartbeat is noticed.
Every breath is appreciated.
Parents learn that life is not measured in decades, but in moments.
In days that begin and end with gratitude.

HRHS forces families to become advocates.
To speak when others are silent.
To push when systems move too slowly.
Because ignoring early signs can cost a life.
And trusting instincts can save one.
Ania’s story is not unique — but it is powerful.
It represents thousands of children born with half a heart and full courage.
It represents parents who learn to live with fear and hope at the same time.
Doctors who dedicate their lives to impossible surgeries.
Communities that rally because one small heart matters.
HRHS is not just a diagnosis.
It is a lifelong battle.
One that begins at birth.
One that never truly ends.

But as long as that heart keeps beating — even at half capacity — there is life.
There is love.
And there is a reason to fight.
Because sometimes, half a heart is enough to hold an entire worl
