Four-year-old Oscar, who has a rare form of cancer, travelled to America over the weekend with the aim of beginning six months of specialist treatment.
However, because of a recently discovered heart issue, he will not be able to receive the therapy - and the brave Belfast boy is now in intensive care.
As his father Stephen explained, Oscar is also suffering from a breathing problem.
"Oscar is okay ... he's weak," he told UTV.
"The problem with his heart is related to his lungs and his lung function is just not great so he's on a ventilator to help with his breathing. Now he is stable but still very weak and he's in danger here so we're just hoping for good news today.
Our focus at the minute is just getting through this new sickness that's cropped up.
"The plan is to get him fit for transportation, medical transportation in an air ambulance I believe so it could be early next week, late next week or even the week after.
"We'll have to wait and see."
Oscar's parents were able to make the journey to Philadelphia after they managed to raise £250,000 towards the medical care thanks to a Twitter campaign which went global.
Stephen said he wants the fund raising efforts to continue, adding that the money will go towards Oscar and other children who need help.
He continued: "Any money that's raised for Oscar is not going to go to waste - it will go to use on helping him get better and ultimately go to any little kids who desperately need it so we are going to keep on fundraising and we will see how it goes."
Meanwhile back in Northern Ireland, lots of people including a number of well known local faces attended a gala ball in Belfast for Oscar on Thursday night.
Belfast Olympic boxers Paddy Barnes and Michael Conlon, were amongst those who turned out at the Europa Hotel for the special fundraiser.
Oscar's dad said they were following the event via Twitter out in Philadelphia and wanted to thank everyone who took part.
"We're so proud that Oscar brought so many people together for a night and want to give massive thanks for everyone who came along," he said.
"It sounds like it was a really brilliant night. We were reading the updates on Twitter all evening and for Oscar it was fantastic and it seems like everybody had a brilliant night.
"There was a few well known faces there and it just sounds like it was a great success."
