Christine McGuinness has said she's been told there could be a genetic link as all three of her children have autism.
Appearing on This Morning, Christine said the couple are doing a documentary with the BBC as they are “exploring this a lot more because we want to know how and why this has happened”.
“Everyone seems to think there's a genetic link there."
Leo and Penelope were diagnosed with autism in 2017, and in 2020 the family were told that their youngest daughter also had the disorder.
Christine, 33, has previously been open about the struggles her children have faced during the coronavirus lockdowns.
And earlier this year she said their speech had been affected.
“They've regressed quite a lot,” she said on ITV’s Loose Women.
“Again, speech doesn't come naturally to them. I spent years going to speech and language therapy with the children and I still do, but they have all gone backwards with their speech and communication skills.
“My daughter, my youngest daughter Felicity, developed a stutter over the first lockdown, which was never there before.”
Christine is set to appear in Tonight’s Hidden Disabilities: What’s The Truth? programme on ITV on Thursday.
