The former glamour model revealed the 18-year-old will learn to live a more independent life at a residential college.
Harvey suffers from Prader-Willi Syndrome and is partially blind.
Mum-of-five Katie says the decision ‘broke her heart’ as she opened up on the difficult decision for her beloved son, according to The Mirror.
The 42-year-old has spent the second half of last year looking around different colleges to find the best fit for Harvey.
Katietold The Sun : “It breaks my heart. I don’t want him to think I’m just getting rid of him.”
The mum-of-five said she’s spent six months visiting different colleges in the hope of finding her first born the very best.
She added: “It’s so upsetting to think I won’t see him every day but this is the best thing for Harvey and we have to think positively.
“This is his chance to live an independent life, learn skills and socialise with people other than me.”
Last year, Harvey started at a residential school for five days, returning home at weekends.
However he moved back home in March due to the coronavirus pandemic.
“When he goes to college he will learn to be an adult. He says now, ‘Mummy, I’m not a boy, I’m a man,'” explained Katie.
The mum said her other four children are ‘excited’ for their big brother but admits they will find it hard when he’s not around on weekends.
Katie said she has always had an ‘incredible bond’ with Harvey who she raised single-handedly after splitting with his father Dwight Yorke.
