Katie Price wouldn't change her disabled child Harvey ''for anything''.

The 34-year-old star's 10-year-old son suffers from Prader-Willi syndrome - which causes him to overeat - in addition to blindness, a growth hormone deficiency and autism and while living with him can sometimes be a challenge, Katie would never want to change who he was as a person.

She said: ''He's my son and I love him, but anyone who knows him knows he is the king of the house. He can be quite controlling. I have to close the car door in a certain way. If someone comes to the front door, they have to ring the bell, or he goes mad. ''Any kids who come to my house tend to be a bit wary of Harvey. He might be sitting there one minute then he'd turn around and whack one of them. He finds it funny. It can be quite challenging but I wouldn't change him for anything.''

Katie is supporting Jeans for Genes day tomorrow (05.10.12), and hopes other people will get behind the cause and help in any way they can.

She told The Sun newspaper: ''People say, 'It's OK for you, you've got money, but my money doesn't make a difference.

''It won't change Harvey's condition. He will still be disabled. What we need is to find out more about genetics.''
