The family live in Loughgilly, a rural part of County Armagh.
Ronan’s part of the care package ended in March 2024, leading to a reduction in the time carers spent in the home.
Donall, who is also autistic and has obsessive compulsive disorder, currently has a carer come in for an hour each day to get him up and dressed.
Alphie told The Nolan Show that Donall brushes his teeth three times and checks his laces six times before he is ready for the day.
Donall and Ronan attend some day centres in nearby towns during the daytime, but at home Alphie is the sole carer.
“Donall doesn’t get up until the carer arrives – you can’t lift a boy in his 40s out of bed and get him up on his feet who doesn’t want to do it,” he added.
“I feel awful talking about them, they’re two great lads.
“I love them dearly.
“The last words my wife said: ‘I’m sorry about this Alphie, look after the children.’
“And that’s something I’ll definitely do.”
