Harry Brinkworth. A 10-year-old boy with autism has received hundreds of cards ahead of his birthday after parents refused to let their kids attend his party. Hannah Brinkworths 10-year-old son Harry is autistic, and she said his birthdays are always difficult to organise. Hannah was trying to arrange a party for his birthday on Tuesday, December 7, when he told her that two children said their parents would not let them go. See SWNS story SWLEboy.
