I’ll never ever understand the handwringing about sugar on here.
My DS is 3- im fortunate he doesn’t actually like “sweets” but loves cake, chocolate, ice cream... we probably have a small treat 3 or 4 days out of 7. He’s very active, brushes his teeth twice a day, and eats around 8-10 portions of fruit and veg. We rarely have tantrums about sweet stuff... and he’ll push away a plate of cake or a bowl of ice cream
as soon as he’s full.
He also knows about healthy and not healthy, and balance. Because we talk all the time about choices - choices between cake now or later, a big fruit salad or a small chocolate etc etc. He makes the choices, and I enforce the rules around them.
I had an eating disorder in my twenties, and it was all because I didn’t understand healthy appetite regulation, or how to make food choices. Food also was a reward growing up- food is totally unemotional as far as DS is concerned. Rewards, sanctions, “treats” are based around activities, TV etc- but never food.
I’d say that you need to reassess how important all of this is to YOU, how important YOU are making it in your DDs eyes, and how far SHE is empowered to understand her autonomy, dietary choices and the consequences of those choices.
