Anything with fruit in has sugars in. Fructose or one of those. Legally the sugar has to be declared separately. Don't worry just ration him to 1 small pot per day and keep an eye on the rest of his diet to know how much sugar he's getting. Get him used to teeth brushing and he'll be fine. Even with no teeth brush because then he'll be used to it when teeth are through. The major ingredient to watch at this age is salt which is far worse than sugar. Also stear clear of artificial sweeteners because they really muck up adult bodies so we can only guess at what they can do to babies and children.
