My eldest goes to preschool, she already attends lots of events where they try to hand out unsuitable sweeties and fruit shoots.
Nothing wrong with chocolate, biscuits and sweets that aren’t choking hazards. All food in moderation.
I don’t allow her to have sweets like lollies or hard boiled sweets, marshmallows or popcorn, as they are all high choking risks. I explain they are for older children, and when she does turn 5 and is at school she will be old enough for them.
Same with fruit shoots/juice/fizzy drinks.
Also I don’t want my 1.5 year old having chocolate, sweets, ice cream etc yet. So she doesn’t. That doesn’t stop my eldest having them.
It’s called parenting your children 🤷♀️
