Zach Tahir, who suffers from Pica Disorder, has chewed his way through carpet and plaster.
And now the five-year-old's mother Rachel, who lives in Salford, has launched a campaign to safe-proof his room after becoming increasingly concerned about her son's welfare.
The aim of the 'Giving Zach a Safe Future' fundraising campaign is to help build a £15,000 specially-adapted extension at the family home at The Mead, Weaste.It would be equipped with a special mattress and a washroom for Zach, who is also autistic and cannot speak.
Their drive - which is aimed additionally at raising awareness of the condition - is being supported by a number of soap stars. The fundraising campaign has been backed by Coronation Street stars including Kym Marsh and Ryan Thomas, as well as Torchwood actor Paul Copley.
Rachel, 32, who also has a two-year-old daughter, said she has been overwhelmed by the support.
'The campaign is really getting some momentum now.
'The support the cast (from Coronation Street) have given has really helped get (the campaign) noticed.'
As well as building a new extension at their home, Rachel also hopes to install a camera so she can monitor her son throughout the night, when his unusual eating habit is at its worst. More than £3,400 has already been raised through fundraising events including a sponsored walk and car boot sale.
Another five-mile sponsored walk from Selfridges at the Trafford Centre to Exchange Square in Manchester city centre will take place on next Sunday.
Designer clothes chain Aspecto has promised to match the amount raised on the day if it reaches £7,000.
Rachel said: 'After an overwhelming response and the generosity of friends, family and the public, I am delighted to say that Salford council have kindly agreed to build the extension on our house to create Zach’s safe room.
'We thank the council for their understanding and I’d now like to use the money raised already and any forthcoming money to purchase the necessary sensory and safe equipment for Zach.
'None of this could have been achieved without the support of local people and we thank you unreservedly.' –DM
Other Weatherfield actors getting behind the fundraising campaign include Jennie McAlpine, Michelle Keegan, Brooke Vincent and Michael Le Vell.
Support on social networking sites has also taken off with a host of other celebrities supporting Zach through his Twitter account, @ZACHgzasf.
They include Looking for Eric star John Henshaw, comedian Justin Moorhouse, Jack McMullen from Waterloo Road and several Emmerdale actors. DM
