Jack P Shepherd’s love child from a one-night stand suffers from a rare neurological condition called Alternating Hemiplegia of Childhood (AHC).

Five-year old Greyson was confirmed as Jack’s son after he demanded a DNA test from now single mum, Samantha Milewski.

According to The Sun, Jack knows Greyson has the disorder that causes temporary paralysis on one side of his body, but his relationship stops at paying maintenance.

A source said: "Sammy doesn’t need his help but you’d think he would have some interest in his own flesh and blood and how he is getting on."

They added: "Sammy is strong enough to cope on her own but what she does struggle to cope with is how a man can turn his back on his own flesh and blood."

Greyson’s condition is so rare, he wasn’t diagnosed until the age of two. Children with AHC are often impacted by developmental delays including intellectual disability.

Samantha is using social media to raise awareness about her son’s disorder.

She wrote: "Hate seeing my lil dude poorly, just stopped him biting an pulling his arm saying mummy arm t go. Another arm mummy. #heartbreaking #AHC"

But she also shared moving pics of Greyson on a good day, laughing and playing at the seaside.

In an interview with The Sunday People in 2014, she said:

"I would like my son to have a father in his life but how can you feel sad for something he’s never had? I guess it’s sad in itself to say that."

Jack has two other children - Nyla, six, and Reuben, two, with fiancee Lauren Shippey.

The Sun’s source said: "Sammy is so brave. She is fighting tooth and nail for Greyson."

We hope Samantha’s campaign helps her get the support Greyson needs.
