The mum-of-two said she was repeatedly asked: "Who's looking after your children?"
Her nine-year-old twins Reuben and Lois were left at home with their dad, former Scottish rugby star Kenny Logan, 42, while Gabby, 41, was working in South America for the BBC.
She said: "People still think it's a woman's responsibility to organise everything. When I was away, some of the mums at school asked Kenny how he was coping.
"No one asked me that when he was working in Australia last year. I'm often asked who's looking after the children when I'm away, yet my male colleagues aren't."
However, Gabby confessed she was secretly pleased to be leaving Brazil when the England football team were knocked out.
She said: "England's early exit from the World Cup was a silver lining because I could go home to see my kids.
"It was good to get back into a routine again, although Lois assumes the role of the woman of the house when I'm away, and she was a bit put out on my first day back.
"She said, 'Oh, Mummy, I missed you', but it was like she felt she had to say it!"
Speaking to the September issue of Essentials magazine, Gabby also spoke of her fears about social media and its potential effects on her children.
She said: "I'm mindful of my children being exposed to the Internet as they're getting older. You worry about what they're going to find. They know about Twitter and Facebook, but they're not interested at the moment."
In fact, she said her own experiences of social media while she was presenting the World Cup had been positive.
At the time the corporation faced criticism over the size of its 227-strong line-up, while others thought there should be more women on the team.
But Gabby said she didn't see the point in sending more females 'for the sake of it'.
She said: "There was an outcry when the BBC unveiled their line-up for the World Cup and I was the only woman. But there were no gaps on the presenting team.
"If you've got someone like Dan Walker doing his job brilliantly, why should the BBC push him out and put a woman in for the sake of it? It happens in other industries, not just football.
"There aren't enough women at the top in science, in boardrooms, or in the Cabinet."
As it happened, Gabby emerged as the BBC's top performer, as her male colleagues faced abuse.
She said: "I just wonder whether I've weeded out the idiots or blocked them all, but during the World Cup I received lots of positive comments for the first time.
"There were a few people who tweeted that I'd asked the wrong question in an interview, which is fair enough, but it wasn't comments about my looks or genitalia I'm glad to say."
