New life, apart: Rare surgery to separate brothers conjoined at head

The parents say they are telling their story to honor the medical staff for taking care of them over the last several months -- and they hope their message can help other parents struggling with a sick child. "To let them know these things that are difficult," Christian says, "can be a blessing in disguise." 

Nicole, 31, worked as a pediatric physical therapist and has been helping the boys with their motor skills, preparing them for being separated. Her favorite thing now is sitting quietly in the living room, listening to them babble back and forth in their bedroom, as if they're talking to each other.  

For Nicole and Christian, life nowadays is a collision of fear and joy, of excitement and anxiety. There are so many unknowns about prognosis and survival the McDonalds have had to find comfort in uncertainty. Christian says they understand that "one or both twins can be neurologically challenged, or they can have a mental or physical handicap" as a result of the operation. 

"We know that is definitely a real possibility, but we're still going to love our boys," the 37-year-old father says.
