With four boys under the age of 10, Steven Rocks was always going to have his work cut out for him. Being a single father doesn't help and having twins with a serious behavioural disorder makes it all the tougher. But losing his job because of the demands of his sons' condition really put the pressure on.

With four boys under the age of 10, Steven Rocks was always going to have his work cut out for him. Being a single father doesn't help and having twins with a serious behavioural disorder makes it all the tougher. But losing his job because of the demands of his sons' condition really put the pressure on.

Mr Rocks, 43, is adjusting to life as a full-time carer. He used to install mobile phone base stations and had a good salary. Now he is up at 6am and spends his days cleaning, shopping, cooking and supervising his sons.

"This is the hardest job I have ever done," said Mr Rocks, at home in Clydebank.

Twins Dylan and Jamie, six, have XYY syndrome, a genetic disorder that leads to violent outbursts and sleep disorder. Sometimes the pair sleep for only an hour at a time and spend their waking hours smashing up the home.

"Once they smashed up the whole kitchen, cups, plates, glass everywhere. I got a call at work for me to come home. My boss said to be me if you go, you'll get the sack'.

"I said sack me, I would rather go home and see that my children weren't bleeding to death'."

Being at home 24 hours a day makes for a lonely life.

"I would love to get some sort of work. I miss the chat and miss just speaking to other adults," Mr Rocks adds.
