The point is its about balance.
I provide all my kids food, I do pack ups as school dinners are shit. So other than meals at friends houses/parties I am in control of their diet.
You need to look at the big picture of what they are eating ie over a few weeks/a month.
In that context a pack of haribo once a fortnight or even once a week is fine. They may also get a pudding with one meal a week (we don't do pudding as routline but there is aalways fruit).
Then say an ice cream or small treat at wkend, the odd biscuit etc. But mainly home prepared food veg, meat, pasta, rice, potatoes, noodles etc. Plus fruit, porridge for bfast, a healthy packed lunch and plenty of exercise ie
Today 2mile scootering to school, swimming lesson at school and running around at playtime. Then a mile to a kung fu class on scooter, the kung fu class and then two miles home on scooter.
Other days they go to park after school or running club or on the trampoline or gymnastics and they bike or scooter to School everyday and it's two miles, so four miles a day. (12 for me as I have pre school run as well).
So the balance is a healthy diet with treats and plenty of exercise. And skinny as whippet kids who are healthy and full of energy.
So no I don't give a shit about a tiny packet of haribo. The kids like it and they always say happy Birthday and thankyou to the giver (bday child gets to stand with teacher and help hand out). And it then goes in book bag and so I can say to save it for after dinner etc.
Once they are at high school they have their own money and can buy what they want and you will be wishing for the day's of one tiny pack of haribo a week.... Though actually my two high school aged kids are pretty good and haven't gone mad. But judging by many kids I see a lot of kids do go a bit crazy. Tbf I remember doing similar at that age but now am conscious of what I eat, still love chocolate but as I said I do 12miles a day just on school run, I go running we go on lots if walks/swimming etc as a family, again getting the balance!!
