More help has been urged for children from poor families after an eight-year-old boy reportedly tried to kill himself when his mother told him she could not afford to buy him a toy. Tse Ngai-wai fell from the seventh-floor corridor of Wang Fai House, Wang Tau Hom Estate, Wong Tai Sin, on Sunday morning while his mother was out, suffering critical injuries. His sister, six, told police he had telephoned a classmate saying he was unhappy before the incident. His uncle told police the boy asked his mother to buy him a Pokemon toy on Saturday night but his mother refused because she could not afford it. Last night, Ngai-wai was recovering in Queen Elizabeth Hospital, where his condition had improved from critical to serious. Yesterday, Ngai-wai's mother, 34, turned away offers of money and toys from well-wishers. She said she did not believe he wanted to kill himself and thought it was an accident when he stood on a stool looking for her to return and lost his balance. The mother and son arrived from the mainland in 1997, but the boy's father died nine months ago. The dean of the faculty of social science at the University of Hong Kong, Professor Cecilia Chan Lai-wan, said: 'Children on public assistance can develop low self-esteem and psychological problems if their material needs are not met and they compare what they have to their classmates and friends. Their problems are ignored by the Government, which provides inadequate support to their families.' Director of the Society for Community Organisation Ho Hei-wah agreed, adding that needy children would look down on themselves in comparison with others. He feared they could be lured into crime to meet their material needs. 'Parents from public assistance families have no money for their children to take part in extracurricular activities such as picnics or even buying things like soft drinks,' Mr Ho said. 'They have to squeeze money from an already-tight food bill to buy their children a pair of shoes.' Mr Ho said monthly welfare grants to needy families should be increased after being frozen for years.
