But you could divide that lot up over a day and the child could still have the same. So e.g.
Breakfast of serial/eggs/toast/whatever the child likes, most of which isn’t that unhealthy.
Snack - a cheese string (I’ve never had one but even the word sounds horrible but to each their own,) Lunch Nutella Sandwich, fruit, maybe a custard cream, and water
Snack half a chocolate bar
Dinner meat/vegetables/healthy sauce with potatoes/rice/pasta depending on the meal, fruit, followed by a pot of joy and water to go with it.
Unless you actually live with the child and know that they have the same for breakfast and McD’s for dinner every night, you cannot possibly judge a child based on one meal.
On MN people go to the other extreme and claim their children have vegetable sticks and hummus for lunch, and that at their children’s birthday parties they serve carrot sticks etc, none of that unhealthy rubbish....
In the real world most people are somewhere in the middle, with children having maybe ham/cheese sandwich, some fruit, maybe a biscuit or piece of cake, and if they don’t have that at school they certainly do at home, and a children’s party being a free for all with biscuits and cakes a-plenty, and harribo in the party bags for good measure.
And reality is that this is just for a couple of years. Once they start secondary the parents literally have no control over what they eat, and if they choose to go and spend their pocket money in burger king every afternoon after school the parents A, are likely never going to know, and B, unless they refuse to give their children pocket money, can’t do a thing about it.
