Paddy McGuinness has revealed his "heartbreak" over seeing his autistic children be snubbed by their peers.
The presenter, 48, and his wife Christine McGuinness, 33, have three children who have all been diagnosed with autism, prompting the couple to raise awareness of such.
The couple - who have been married since 2011 - are parents to eldest child Felicity McGuinness, six, as well as twins Leo McGuinness and Penelope McGuinness, eight.
Discussing his children, Paddy - whose wife announced that she had been diagnosed with autism herself last year - has opened up about a particularly "upsetting" experience.
He explained: "It's upsetting as a parent when your child goes up to another child in that lovely way and introduces themselves, which is the most normal, nice thing to do ever.
"But most kids will look at that as: 'What the hell is going on here?' They don't understand it. As a parent, it's heartbreaking."
The Question of Sport host opened up about such circumstances on his Table Talk podcast. He revealed during a recent episode that he had experience it "a million times."
The presenter however suggested that he wouldn't want his children to act otherwise, commenting: "I'm glad my kids still do it." He added that he is glad they are "polite."

Paddy and Christine have raised awareness of autism in recent years, including in their documentary Our Family and Autism, which aired on the BBC a few months ago.
It saw the couple meet other parents, experts and people on the autism spectrum, with the programme shedding light on the condition. It received much praise from viewers.
Following the release of the documentary, Paddy and Christine have launched their podcast, Table Talk. They have discussed their life with autistic children on recent episodes.
This included discussing the difficulty getting their children to eat breakfast, prior to their diagnosis. Paddy stated in one episode: "I couldn't get the kids to eat anything."
He admitted that he was concerned what their teachers would think if they found out the kids weren't having breakfast, fearing that he would be deemed a "bad parent."
Paddy revealed that the couple have to cut food in a particular way otherwise the children might not eat it, with their kids said to be keen on eating chicken nuggets and fries, amongst other dishes.
It was reported that Christine said they still have to be aware of sensory aspects of food and autism, with the couple having to separate food for their kids, for example.
The new podcast Table Talk with Paddy and Christine in partnership with McCain and Family Fund is out now.
