Christine McGuinness has shared that her and Paddy McGuinness’ youngest child Felicity has been diagnosed with autism.

Her older children, twins Penelope and Leo, are also autistic having being diagnosed in 2017.

The 31-year-old posted a poem to her Instagram account which declared her children were "perfect", while captioning the post: "Recently our youngest daughter Felicity was also diagnosed with autism, three years after our twins Leo and Penelope were diagnosed.

"Going through this journey again does still bring some heartache knowing all three children will face challenges and difficulties that others won’t."

"But ultimately I feel confident as a family we are in a much stronger place, we are able to use our experience and knowledge as power helping us to feel well prepared. We are here to love and support our three extra special children and I thank god every day these babies are mine. Proudest mummy #Autism #AutismAwareness #3superstars #KnowledgeIsPower."

McGuinness divulged last year that she believed Felicity had been showing signs that indicated she was on the autism spectrum.

She also shared an important milestone with her Instagram followers over Christmas as she was able to decorate the family home with a tree for the first time in years.

The mother-of-three disclosed that her offspring had struggled in the past due to being "upset by the changes" and disruption to their routine.

She's also been outspoken on issues concerning her children after her husband Paddy revealed a stranger had criticised him for parking in a disabled space while with his children, as he questioned the presenter's need for the spot.

McGuinness appeared on BBC Breakfast in the wake of the incident where she explained she had such experiences "every weekend", but that she tried to "educate" people who didn't understand invisible needs.
