You could mix it up a bit (e.g. put the yoghurt with the puffed rice). Also you could grind some flaxseed and nuts (if your DD isn't allergic to other nuts), and sprinkle that onto the yogurt / puffed rice combo or even onto fruit which is nice. If you are using natural style yoghurt you could add a small amount of honey as well. You could smush soft fruit like berries onto toast as an alternative to jam, or could try marmite / vegemite. You could make a savoury kind of porridge with soft vegies like pumpkin in it. Or you could grill tomato halves. Of course there is always the traditional double espresso in a sippy cup
