The brother of a four-year-old boy whose body was found mummified in his mother's bedroom told a jury how he saw the little boy eating the contents of his own nappy and sleeping in a buggy that stank of urine.
Qaiser Khan, 22, was giving evidence on the third day of the trial of his mother Amanda Hutton, who denies the manslaughter of her son Hamzah Khan.
Hamzah's body was found in a travel cot in his mother's bedroom in September 2011. He had died 21 months earlier, in December 2009.
Mr Khan told a jury at Bradford Crown Court how he went to the house between December 2008 and March 2009. He said Hamzah slept upright in a urine-soaked buggy that "stank".
Mr Khan said his brother was left in a dirty nappy and he witnessed him eating the contents. "Hamzah appeared neglected," Mr Khan said.
He explained to the jury: "I was only at the house for a couple of days. The buggy smelled so bad of urine I got disinfectant and cleaned it out."
Mr Khan was also asked about a text message sent from his phone to Hutton in December 2008.
Paul Greaney QC, prosecuting, said the text said: "Watch out Monday you bitch. I'm going to go to the police station to report you for child neglect and abuse. Look at Hamzah." Mr Khan said he did not remember sending it.
Asked by Stephen Meadowcroft QC, defending, if he was exaggerating what was happening at the house because he had a bad relationship with his mother, Mr Khan said: "I've seen this with my own eyes."
Mr Khan told the court that when he was aged about 13, he was made to drink "mouldy, off milk" by his mother as punishment. He said his mother would spend her days drinking. "She would go upstairs and drink and then I wouldn't see her for most of the day," he said.
