More than £28,000 has already been raised for Joshua Granger's treatment, but now that surgery has been set for November the big push is on.
The nine-year-old has cerebral palsy and has to wear splints to help him walk. He also gets painful injections in his legs every three months.
But he could be given a new lease of life through a surgical procedure carried out at a hospital in Missouri.
As previously reported in the Evening Times, the Pollok youngster's family has embarked on a campaign to raise £50,000.
Since we highlighted his plight Joshua's mum, Ashley, has been overwhelmed by offers from people asking what they can do to help the St Marnock's Primary pupil.
The date of the operation has been forward by four months - but it will only go ahead if Joshua's family can raise a further £22,000.
Ashley, 26, a pupil support assistant, said: "It is nerve -wracking now that we are awaiting our appointment date.
"Joshua is excited he will have a new start for Christmas, and he is looking forward to visiting America.
"We are aiming to raise another £10,000 in the next couple of weeks.
"We are working really hard to raise the money and hope people will continue to donate.
"Family and friends have rallied round, and we have also had many donations from strangers.
"We are still waiting for our exact date for the operation, but we know it will be happening in November.
"Operation dates are sent out month by month, so we should find out our date soon."
Ashley said the family had received a lot of support from local people and beyond.
Joshua was born 10 weeks premature and weighed only 3lbs 6oz, so he spent weeks in hospital.
But when Ashley took her son home, she noticed he was not doing things a baby should.
Doctors later diagnosed Joshua with cerebral palsy.
Ashley said: "Since then, Joshua has had to learn to use a walking frame.
"It has been hard work, and we know there is a lot more ahead but it will be worth it."
The operation, performed by world renowned Dr Park, will see him perform a procedure to lengthen Joshua's calves.
The operation will involve around four weeks in America, for the procedure and follow-ups, and then physiotherapy at home.
Ashley and her partner, Craig Greenwood, and their one-year-old daughter Rebbekah will join Joshua on the trip.
