flavouring homemade yoghurt

[thefootofourstairs]

I got a yoghurt maker for Christmas :) and have made my first batch, which to me tastes lovely plain .
Ds2 is used to eating very high sugar shop bought ones , no bits allowed and lots of them ( teenage , hollow legs ) and wasn't impressed with my offering .
I need ideas of how to flavour the yoghurt so that it is healthier, but still appealing to DS2 .

Could you make a fruit puree to stir in? Total ball ache but if bits aren't allowed you could make lots and freeze in ice cube trays to have a small amount to defrost and add in.

A small spoon of honey or maple syrup stirred in - gradually reduce the amount as he gets used to it being less sweet
Add fresh fruit like sliced mango, peaches, mashed berries or stewed fruit like apple,pears and plums
