We have so far not allowed our toddler (20-months) any foods that contain sugar (chocolate, cake, sweets, sweetened juice, etc.) on the premise that consuming sugar is not needed and only causes trouble for the parents, in terms of risks of making the child a picky eater, trouble at mealtime caused by sweets in between meals, and health concerns like tooth decay. This also means that we politely turn down any sweets offered to the child by third parties. (It's amazing how rudely insistent strangers (e.g. waitresses) can be!)
We do allow normal healthy foods that taste sweet, like fruits and teas, but no fruit juices and no deliberately sweetened foods.
Obviously we can't keep our son sugarless forever, and don't aim to anyway. So my question is this:
Until what age does it make sense to avoid sugar? Why?
Also, what strategies are effective to postpone the introduction of sugars?
Come to think of it, one could ask almost the exact same question about spices. They're not unhealthy of course, but they're only needed for taste and therefore carry the same potential of causing a picky eater.
