The doting parent posted a snap of her first born wearing a hospital gown to her Instagram account, accompanied by the caption: ‘My brave boy.’
Later, the mum of five shared a snap of the pair of them and the message: ‘Love him sooooo much.’
Although it’s unclear exactly what Harvey was in hospital for, Katie has previously spoken out about the difficulties her son faces with his many disabilities, saying she worries for his future.
Back in August, the 37-year-old told Channel 5 that looking after her 13-year-old son is a ‘challenge,’and that she can’t bring herself to put him in someone else’s care.
She said: ‘People tell me it's normal and so many use respite to have a break with their kids but I won't do it, I don't want to leave him.
'I won't do respite with him yet. I don't want to feel like I am letting him down by letting him go while I go and have fun with the others.'
Harvey suffers from autism, is partially sighted and can’t walk far unaided. He also suffers from Prada Willi Syndrome, which causes mood swings and other complications.
Katie said: ‘If you have a child with disability your life does change, it's not easy if my other children want to go to a theme park and Harvey doesn't want to go, it might ruin their fun.'
