Before you begin, find a baking tray fits into your freezer.  Cover the baking tray with tinfoil or baking paper.

Measure the oats, coconut and sesame seeds into a bowl and mix well.

Peel the bananas and cut them into bite sized pieces. A quick note on knives here - I allow six year old Small Child to use a small sharp knife under close supervision.  I believe that teaching your child to use a knife safely is preferable to keeping them away from the altogether, but it really does depend on the individual child - use your judgement to decide whether your child is ready to use a knife.  With this recipe, a blunt butter knife will also work just fine on banana.

Dip each piece of banana into the oats and turn until well coated in the oat mixture.  Place on the baking tray and repeat until all the banana pieces are gone.

Freeze for 2 hours or overnight then serve frozen.  Once frozen solid, pop any leftover bites into a bag and keep frozen until ready to use. Best used within a week.
