Ruth Charles uses a striking phrase when she discusses the origins of childhood obesity; "things that have been allowed to happen."
Things that have been allowed to happen, she explains, are usually small; little bad habits that can begin from the moment a child is born.
So for example, putting an extra scoop of formula, some baby rice or a crushed rusk into the bottle of a wakeful, formula-fed child may help your child sleep more soundly – but it also means you're giving your child extra calories that he or she doesn't need and potentially predisposing them, both psychologically and physically, to weight gain and a life-time of over-eating.
That's partly because the more calories a child is fed, the heavier the child will be.
"You're also stretching the child's stomach so that, very quickly it takes more to fill it," explains Charles.
You're also habituating the child to not feeling satisfied until it has eaten too much.
"If a child is used to that feeling they won't feel satisfied until they feel stuffed."
And then there's weaning – evidence shows that Irish weaning practices often tend to rely on commercial salty snacks or sweetened sugary drinks, she says.
"You'll notice toddlers in buggies carrying a packet of soft, crisp-type snacks or a carton of juice. That is all extra calories. These snacks are high in sugar, salt and fat," she says.
Something has also been allowed to happen to the traditional family mealtime as time-poor parents are often not cooking or eating with their children.
"Traditional routines have changed," says Charles, pointing to the fact that many children now eat with other children in a childcare setting, or on their own before bed.
"They may not see food being prepared from raw materials. I meet a lot of children who don't know where their food comes from. They see food coming out of a box or a packet.
"If you ask them where beef comes from they'll say 'the shop' or 'a packet'.
"You have children growing up who don't understand the basics of cooking."
If your child is not exposed to shopping for and cooking raw materials in a traditional family environment where the food is eaten by the family together, they won't sit down and eat normally.
