I would love some advice on my 6 year old please. He has been helping himself to sweet food from the kitchen, eating in secret and hiding the packaging.
We used to have a box of sweets/chocolates which the children would receive occasionally and we noticed some missing then later found the wrappers hidden in his room. We explained it was not good for our teeth or bodies to eat so many sweets then removed the box so it was no longer in the house. A few weeks later, he progressed onto climbing on worktops and taking the few biscuits and chocolate we did have from a high cupboard in the kitchen. We did not make a big deal but chose not to replace them when they were finished. When there was little else he could access, he started taking dried fruit from our baking cupboard. This weekend, he climbed on unstable shelves to obtain chocolate spread to eat with a spoon and was having honey by itself this morning. He does this when the rest of the house is asleep and I dread to think of the danger to him had one of the shelves fallen
For background, we aim to feed the children a healthy diet by modelling the habits we want them to develop. We do not eat much biscuits/cakes/sweets ourselves but where we do, they are always offered as well. I don't believe I am really strict but I do not give unrestricted access to food containing sugar as they cannot self regulate yet. We regularly talk about which foods are good for our bodies, help them grow etc and put the focus on this rather than demonising the foods we should eat less of.
I am confident it is not a hunger thing as food is not restricted. He is allowed as much as he wants for all meals, I send a packed lunch which contains all food groups - this comes home eaten but not entirely finished so I know he has more than he needs. The children have open access to all food within their reach - fruit, nuts, cheese, crackers, home made snacks are the types of food they can help themselves to at any time of the day without asking permission.
He is of a normal weight, healthy and very active. I am not concerned about weight gain in the short term but want to nip this in the bud before it starts to cause longer term issues. How do I approach this as calm conversations have achieved absolutely nothing?
