Christine McGuinness has revealed her young son Leo, who has autism, was left "seriously underweight" due to his sensitivity around food.
Christine, 34, and television presenter husband Paddy, 48, share three children, twins Penelope and Leo, eight, and Felicity, six, who have each been diagnosed with autism, and the pair are open about the ups and downs they have faced as a family.
Speaking to Mail Online, the model revealed how Leo became underweight from vomiting food up regularly.
She explained how all her children are over sensitive when it comes to food, including the taste, smell and texture of it.
"We had vomit after vomit for years. It felt like we'd feed them, and then we'd clean it up to the point where Leo was seriously underweight, and it was affecting his health."
She added: "He wasn't getting the right vitamins and we discussed putting a peg in [the stomach], and just having that conversation at the time – I remember it being heart-breaking.
"And we didn't have to go that route, and even now they still eat very limited, but they eat enough, and he has vitamins and milk shakes to help him get everything he needs."
Christine - who shared her own autism diagnosis last year, revealed in March that she hasn't been able to relax on holiday since her kids were born, because she worries about them too much.
The couple only go away with them for short periods, with Christine having said recently: "We started off with a little holiday in Preston, and then gradually we got to Spain."
Christine added: "I want to get to the point where you relax and enjoy it. I don’t think I've done that. I've been tense."
Speaking on their Table Talk podcast - in partnership with McCain and Family Fund - the couple advised other parents looking to go on holiday with disabled children to do so "gradually."
Further sharing advice, Paddy commented: "Over-pack just in case. It's just worth it for your own peace of mind."
The couple took part in their own documentary, titled Our Family and Autism, on the BBC a few months ago. It shed light on the condition and received praise by viewers.
The programme saw Paddy and Christine meet other parents, experts and people on the autism spectrum. They have since launched their own podcast, Table Talk.
Recent episodes have seen them discuss their life with autistic children, including mentioning the difficulty getting their children to eat breakfast, prior to their diagnosis.
Paddy admitted he'd been concerned about being deemed a "bad parent" over this, with him worried what their teachers would think if they found out the kids weren't having breakfast.
He revealed that the couple have to cut food in a certain way, to encourage the children to eat it, with their kids said to be keen on chicken nuggets, among other foods.
