String cheese, yogurt pouches, fruit leather, and mini carrots with hummus are some crowd-pleasers in our house.
I also started freezing fruits like grapes, berries, and bananas in batches. They defrost quickly and keep the appetite satisfied with something cold and sweet, plus they're easy for little hands to pick up and eat.
Also a fan of making 'snack plates' - a collection of safe-to-eat items from the fridge that my tot can graze on - usually consists of cherry tomatoes, cucumber slices, bell peppers, carrots etc. Anything brightly coloured seems more fun! Sometimes I'll add a little something extra special like a couple of chocolate covered almonds or a few goldfish crackers to keep things interesting.
