"I was shocked. I thought it was very odd. I thought … I didn't know what to think of it, really. It's not something you expect to see … a situation you expect to see a father and daughter in."
In 1993, she first brought forward the allegation during the custody battle between Allen and Farrow.
"His face was very close to her private area," Stickland said.
Later, Dylan told her mother she was molested by Allen in their attic, the same day Stickland claims she saw the inappropriate behaviour.
After being tracked down, now living in the United Kingdom, Stickland agreed to speak on the podcast.
Stickland was tracked down by Amy Herdy, investigative journalist who led research for HBO's bombshell docuseries.
Stickland did not appear on the doco series because it took her a while to build the courage to respond to Herdy.
"You don't think something all those years ago is going to come back, so it was a shock," Stickland said.
"I didn't respond very quickly because I had to let it sink in … I felt, you know, it's something I kind of really need to do, because if I leave it and don't, it will probably eat away at me."
Stickland described the Allen and Farrow household as "lovely".
"Lovely children, they all got along well together," she said of the Farrow children, who were around the same age as the Pascal children she was tasked with watching.
"There never seemed to be any sibling rivalry. The older children I would say had fun with the younger ones. It was just very happy. I wouldn't say it was troubled at all.
"I thought [Mia] was lovely. She was a very soft-spoken, gentle lady. Very attentive. You could tell it was so obvious that she adored all her children."
The day Stickland says she saw the interaction between Dylan and Allen was not "normal behaviour".
After witnessing the interaction, Stickland spoke with boss Casey Pascal.
