Fruitickles are sadly another genius marketing tool in the vein of fruit winders & the like-called something fruity, made with 100% fruit to fool us into thinking we're giving our kids something healthy. Once you remove the fibre/water/goodness from fruit and cook it down you intensify the sugar (which isn't better because it's fruit sugar), it's the same damage to your child's teeth and body as a pack of haribo!
Each little pack contains over 4 tsp sugar; a primary aged child should be having no more than 6 tsp a day anyway, so disengenuous products like this masquerading as 'fruit' are adding to the tooth & general health problems for well intentioned parents, as they probably don't even register them in the same category when later deciding that the child can have some cake/sweets/biscuits as hasn't had a treat that day.
Can you tell I have a huge issue with such products! My fruit-phobic sonwas given bear yoyo by my mother as she thought he was at least getting 'some fruit'. Far better to up the veg intake and hide whole fruits in homemade smoothies/pancakes/muffins etc. At least that way they're getting the nutrients and the fibre in order to be able to deal with the naturally occurring sugar.
As for healthy snack-chunk of cheese, carrot batons, pot of sweetcorn, cherry tomatoes, cucumber/pepper sticks etc. Or if you want to give a sweet treat, make a banana loaf (use wholewheat or spelt flour, less sugar and natural fat like butter/oil-Google for a healthier version), and cut up into small slices and freeze. They will still be getting some sugar but not as much and with other good stuff too. It'll be more filling and satisfying as well.
