Niki, also mum to Ella-Mae, 12, Bradlee, 10, Archie, six and four-year-old Poppy, said her daughter remains a happy little girl. About one in 200 babies is born with a rare chromosome disorder.
Chief Executive Beverley Searle at Unique - a chromosome disorder support group - said Olivia's "super rare" disorder is the first they have come across in the entire world.
She said: "This is a super rare case. Olivia has a condition that's in the same group as people with '6p' deletion.
"On our worldwide database there are just 100 people with the '6p' deletion.

"That's out of 15,000 chromosome disorder cases worldwide - and there may not be anybody out there the same as Olivia. People feel isolated when they are diagnosed with rare disorders.
"I can't comment on this individual case or whether Olivia is 'bionic' - but we are here to help her and her family to alleviate symptoms.
"As a group we try and find matches and provide information for families, which can be great for friendship and local support.
