Christine McGuinness has told of her heartbreak after a woman complained about her autistic twins making too much noise.
The model, who is married to TV star Paddy McGuinness, said the stranger moaned about the noise five-year-olds Leo and Penelope made at a play centre.
She claimed the woman complained “four or five times” about the youngsters’ “happy squeals and laughter”.
She wrote on Instagram: "When you've had or have non-verbal children or children with delayed speech you appreciate any sound they make.”
"I consider myself very fortunate that my children are now verbal, their vocabulary is not like other children their age but they're doing absolutely amazing,” she added.
"I had silent children for years so to hear someone complain about their noise, when they're inside a play centre which is another challenging environment for them, it's heartbreaking.
"Their 'noise' was just happy squeals and laughter! Yes my children can sometimes be louder than others, even though they don't like noise themselves, but let children be children!
"I wish the woman complaining could have just opened her eyes to see my very happy, content children simply expressing their joy."
She added in a video clip on the site: "I just think we've still got such a long way to go to open people's eyes and see past the autism.”
McGuinness revealed in July last year that the couple's twins had the condition.
In a touching Instagram post to mark their fourth birthday, she said they were "totally unique and fantastically awesome".
The couple are also parents to daughter Felicity, who was born in 2016.
