Helen Smith, 45, from South East London
As a child, my youngest son was a huge challenge.
Sean was born on 20 July 1997 and from the get-go, I just had my hands full with him.
He was constantly crying and pulling things.
And boy did he hit the terrible twos hard.
He would have the worst tantrums until he got what he wanted and regularly attacked his siblings, Charlotte, now 27, and Adam, now 26.
I couldn’t understand why he was like it.
The eldest two were such calm, lovely children and rarely even misbehaved themselves.
But Sean was the opposite, he was simply out of control.
When he was three years old, he spat at my mum Christina, 74, after she asked him to put all of his Christmas presents upstairs.
