There's a recipe somewhere for porridge fingers.
I used to make oaty chews (not for breakfast but for snacks) and there are several recipes on the baby recipe threads for these, just like flap jack but no honey/sugar/syrup.
I'll hunt them down if you're interested?
I used (and still do at 3yo!!) Cow and Gate "my first muesli" it's labelled from 10 months. Added a very small amount of milk, then stirred thoroughly, you have to judge how much milk, it thickens a little over a minute or so, when it's a bit like play doh pack it down, cut into sections and roll each into a ball. Mine loves them, it's fortified cereal and sugar free. he's actually only just started eating it as 'muesli' with a spoon rather than muesli balls as finger food, he loved the balls so much.
This is a quick on to make on teh day where as the oaty chews are a make in advance thing, you need more time to make and oven bake them but once you've done a batch you can freeze them and just takes a couple of hours to defrost and they also keep really well in an air tight container, I kept them in the fridge for several days.
