And the manager said she washed outside the boy's mouth, not inside.
In her summing up of the case this morning, Judge June Jelas said the allegations were not about tapping or directing children's hands.
The charges related to a pattern of behaviour where Abraham would strike a child to the extent other staff members could hear the force.
One of the workers, Jennifer Wong, recalled seeing Abraham smack a boy on the hand.
When he continued to cry, she allegedly hit him on the bottom and said he had "nothing to cry about".
Wong said she also saw the manager tape a girl's mouth shut because she was being noisy and force-feed children with a spoon then forcibly move their jaws with her hand.
During her evidence, Wong frequently got very upset and had to be excused to compose herself.
Judge Jelas told the jurors they shouldn't allow feelings of sympathy for Wong or prejudice that she hadn't spoken out earlier affect their decision.
The judge gave a demeanour direction and said they should be careful not to "jump to conclusions" about Wong's evidence.
How she gave evidence should not be the only factor they took into account, she said.
"It's been shown over time that looks can be deceiving."
She reminded the jury of the presumption of innocence and that the onus was on the Crown to prove Abraham's guilt beyond reasonable doubt.
The defence did not have to prove her innocence, the judge said.
In his closing yesterday, defence lawyer Graeme Newell said no one was able to corroborate Wong's testimony that Abraham put tape on a girl's mouth.
But Judge Jelas said there was no requirement to corroborate the evidence if the jury decided to accept it as accurate.
The judge said the jurors would also have to decide if there had been forced used, that it was for the purposes of preventing or minimising harm to a child and not for the purpose of correction.
