Incredible moment twins conjoined at the head look at each other for the first time as they make historic recovery from 27-hour surgery to separate them

• e-mail

They shared every second of their lives together until last month. 

But Jadon and Anias McDonald, twins conjoined at the crown of their heads, never caught a glimpse of their closest companion. 

In October, the 13-month-old boys were successfully separated in a grueling, life-threatening 27-hour operation at Montefiore Hospital. 

And a month later, as they make an historically rapid recovery, they have been pictured looking at each other for the first time.

Staring, open-mouthed, they both look stunned.

Who are you? Jadon and Anias McDonald look at each other for the first time after surgery

They shared every second of their lives together until last month. But Jadon and Anias , twins conjoined at the crown of their heads, never caught a glimpse of their closest companion

The pair will be moved to a rehab facility shortly after Thanksgiving, six weeks after surgery. 

It is the fastest recovery for separation of craniopagus twins (conjoined at the head) in history, beating the previous record of eight weeks. 

Jadon is already ready to move, as he is now vibrant, active, and energetic, pulling at his bandages and playing with anyone who enters the ward.

Anias, who was already struggling before the operation, is having more difficulties, regularly contracting viruses and infections. 

But their surgeon Dr Philip Goodrich said he believes Anias will pull through, and he thinks Jadon is a great force of energy for him at this time. 

'Separating the two is probably not a good idea at this point,' he told CNN.

The boys were born via cesarean section last September near Chicago, Illinois. They were attached by the crown of the head. 

Nicole and 37-year-old Christian insisted the boys were perfect as they were.

But in order to let them lead a normal life, they traveled to Montefiore Hospital in the Bronx, New York, to have one of the world's most esteemed surgeons perform the incredibly rare operation to separate their heads.

The operation costs $2.5million.   

This is the moment Nicole McDonald was able to hold Jadon for the first time

Anias was still struggling with infections and seizures, so could not be held last month 

'This is so hard. I'm not going to sugarcoat it,' Nicole said before the operation.

Anias and Jadon, who have a three-year-old brother Aza, were technically called 'craniopagus twins' - a phenomenon that occurs just once in every 2.5million births.

Based on national statistics, it is astonishing they made it to 13 months.

Around 40 percent of craniopagus twins are stillborn. Of those that survive, a third die within 24 hours of birth. 

If craniopagus twins survive that point, there is still an 80 percent risk they will die before the age of two if they are not separated.

Separation meant one or both of the twins could suffer developmental complications. 

Anias is certainly have troubles. 

For a long time, Nicole couldn't hold Anias because he had been slower to recover from the surgery and still has his breathing tube in.

Doctors warned this might happen because Anias suffered breathing issues, seizures and heart problems even before the surgery.

After the procedure, he continued to have seizures but doctors put him on medication that stopped those attacks last month.

Based on national statistics, it is astonishing they made it to 13 months

She did, however, get to hold Jadon, and described the moment in an emotional post on Facebook.

She said it was always her goal to be able to rock her 13-month-old son Jadon - something she could not do when her sons were conjoined at the head.

'For over 13 months, I've dreamed of this moment,' Mrs McDonald wrote.

'I looked down at Jadon's angelic face and saw him in a way I'd never seen him before.

'He whimpered for almost the whole two hours I held him because he had just been extubated, had the area under his scalp washed out and had been weaned from the good pain meds.

'But instead of wrapping my body around him in his bed, I wrapped my arms around him and rocked. One of the most profound moments of my life.'

The operation was performed by Goodrich, a neurosurgeon who specializes in separating conjoined twins at the head.

Dr Oren Tepper, a plastic surgeon, was in the room to reconstruct the skulls and stitch each head closed.

The team has spent months practicing and planning their strategy using a physical 3D model of the boys' heads, plus computerized 3D modeling, where they can look at different scenarios. 

A Go Fund Me page was made to help the family with the cost of the expensive surgery.

The couple, who live near Chicago, already have a three-year-old son, Aza

Their twins were born via cesarean section last September
