Cheerios are a big favorite here, but really she'll try anything she sees her big sister eating LOL (usually a fruity-flakey-muesli type thing, whatevers on special that fortnight). Sometimes I give her the cereal dry in a cup and she's happy to crunch her way through it with a drink of milk on the side. We have never done rice bubbles, cornflakes, frootloops, cocopops or any of those highly refined & sugared ones & I recommend staying away from them for as long as you can.

Have you tried the flavored instant porridge sachets? Ok so they're not the healthiest thing but you could do worse in the cereal aisle. My DD likes to help mix it and watch it going round in the microwave.
