She suffers from a severe form of epilepsy called Dravet Syndrome
A medicinal cannabis campaigner, who walked from Cork to Dublin to raise awareness, says her daughter will begin treatment in The Netherlands today.
Vera Twomey's child Ava suffers from a severe form of epilepsy called Dravet Syndrome, which can be treated with medicinal cannabis oil.
She posted a video to Facebook, confirming the seven-year-old is to begin receiving CBD and THC medication today.
"We've been here now for the last few days and today we had a doctor's appointment and we have begun Ava initally on her treatment.
"Her CBD and THC medication has been prescribed, and that medication will be issued tomorrow - and we'll begin Ava on the combination of CBD and THC medication in the morning."
"Don't give up the ghost on legalisation of medicinal cannabis in Ireland...if anything, coming over here has just made me see just the ordinary people in this country they think it's a fantastic alternative, a fantastic treatment - and that's the way that it should be".
She also thanked all the people who have offered help and support to them.
Speaking to Newstalk Breakfast earlier this month, Ms Twomey said her daughter's seizures had reduced by as much as 90%.
"We're very, very sad that we've had to leave the country. We tried so hard, all we wanted to do was to stay at home," she said.
Vera explained how CBD oil works: "There are receptors in all our bodies to receive CBD oil, and when the CBD is administered... it actually calms the body, it reduces inflammation in the brain.
"When we began the CBD oil in October of last year our daughter had 11 consecutive seizure-free days.
"Her seizure control has been magnificent really since... I'd say her seizures are down by about 80 to 90%."
Administering CBD oil in Ireland is completely legal, but the THC component of the medicine is not. THC is the principal psychoactive constituent of cannabis.
