1. Preheat your oven to 180°C (350°F). If you prefer, you can also use a toaster for a quicker option.
2. If using the oven, lightly grease a baking tray with olive oil to prevent sticking.
3. Cut the whole grain bread into small squares or shapes that are easy for your toddler to handle. Aim for about 3 cm by 3 cm pieces.
4. In a bowl, mix the soft cheese with the diced apricots, combining them thoroughly to distribute the fruit evenly through the cheese.
5. Spread a generous amount of the cheese and apricot mixture on each piece of bread. Make sure the topping is thick enough to keep it from falling off easily.
6. Arrange the topped bread pieces on the greased baking tray (or on a plate if using the toaster). If you're using cinnamon for additional flavor, lightly sprinkle it over the tops.
7. Bake in the preheated oven for about 15-20 minutes or toast until the edges are golden and the cheese is warm and slightly melted. If using a toaster, toast until golden brown on the outside.
8. Allow the bites to cool slightly before serving to your toddler, ensuring the cheese isn't too hot.

Summary:

Possible Side Effects/Allergies:
Be mindful of possible allergens; cheese can be a concern for some babies, so ensure your child is not allergic to dairy. Always consult with a pediatrician if you're unsure about suitable foods for your toddler.
