The birth mother of missing toddler William Tyrrell was seen laughing as she walked into court on Monday.
Karlie Tyrrell, 29, was due to be sentenced for assaulting a police officer and using offensive language in a public place after pleading guilty earlier this month at Burwood Local Court.
But Magistrate M Richardson delayed her sentencing until March 19, and ordered she undergo a pre-sentence report.

The 29-year-old was arrested and charged on December 22 last year after allegedly spitting on a police officer and swearing in public
Tyrrell was arrested following a heated late night incident at a Ryde shopping centre on December 22 last year.
Security guards rang police for help with a woman who was ‘acting aggressively toward customers’ just after 9pm that evening, a NSW Police spokeswoman said.
When officers arrived, Ms Tyrrell ‘repeatedly swore at the officers in the presence of two children’ before spitting on an officer’s face, police alleged.
Police facts tendered to the court say the accused became very angry when an officer asked one child in her company about marks on his legs, and said: ‘none of your f***ing business’.
She then spat on a second female officer’s right eyebrow and cheek after shouting ‘Ryde coppers lost my son you c****’.

‘I recently found out I suffer from panic attacks which played a major part into my behaviour but I’m not making any excuses,’ she wrote.
Her son William Tyrrell is believed to have been abducted from his foster grandmother’s yard in Kendall, on the mid-north coast of NSW, on September 12, 2014.

Both William’s foster and biological parents have been ruled out as suspects in the police investigation into his disappearance.
On Monday she told the court through a handwritten letter she suffered panic attacks, which she said played a ‘major part’ in her behaviour
