The actress's alter ego Katie Macey has a horrendous ordeal ahead in upcoming episodes as she falls down a mineshaft and is left trapped for days.
Speaking on Daybreak this morning (November 22), Winward confessed that she may ban her 7-year-old daughter Mia from watching the storyline, which includes scenes of Katie trying to make her escape by crawling through a tunnel in excruciating pain.
Winward explained: "I don't know what I'm going to do about this. She'll probably badger me into watching it - she won't listen to me at all! But I think it's a bit much. Tonight might be okay, but tomorrow's episode, no! I think that'll be too much for her - it gets a bit too much."
On watching the episodes herself, she said: "I haven't seen it put together yet, so tonight's going to be my first viewing as well."
Winward, who joined Emmerdale in 2001, added that she is still delighted to be working at the soap.
She said: "I've been there about 11 years now. [It's been] very eventful. But they keep finding things for her to do, which is great.
"I absolutely love it, it's a great, great place to work. I've got all my best friends there, and the cast and crew are awesome."
The 27-year-old also joked that Katie is lucky her mineshaft fall didn't take place before her wedding last month.
She laughed: "Usually something happens on the day of the wedding, so she was given a few weeks which in soapland [is actually] a great marriage!"
Emmerdale airs Katie's mineshaft drama tonight (November 22) at 7pm and 8pm on ITV1.
