Just some other options for breakfasts which we love and would work for a younger baby - we make our own dropscone (Scotch Pancake) mixture - its got milk, eggs, flour and a little bit of sugar and tiny pinch of salt, so pretty good really. I make a batch at the beginning of the week and it lasts for 4 or 5 days in the fridge.
Then you can serve it with honey, jam (OK sugar but mmmmm) or chopped up fruit.
That, porridge and cheeriups and raisins are our favourite breakfasts. We've given him Cheerios (we call them cheeripus as he loved them so much when he was little we would bribe him out of a grump with them!) from quite a young age - despite the sugar content the rest of his diet was largely home made, and he had no sweets or chocolate etc until more recently, so I figured in the overrall picture they weren't a disaster.
And someone commented on the supermarket own brands having less salt and sugar - that is generally true I've found, although I suspect its from an economy point of view rather than a vested interest in our health!
