I don't do the raw food diets, mainly because I am seriously addicted to cooking. grin You can get great food though and I love trying out some of the recipes. We try and do foods from scratch. We started out with the theory if you can't look at it and know where it came from, we should probably avoid it. For kids, I would be hesitant to say a raw diet or the paleo diet is good for them because I don't know enough about the diets. Kids need a good balance with lots of the right fats and oils, carbs, nutrients etc. When people try and stick to a limited diet things can get missed out. If you were covering all bases its probably workable. You would have to be very on top of it though.
For breakfast we do things like eggs, porridge with soaked rolled oats, rice, soaked oats with grated apple, honey, yogurt etc
Basically my rule with the kids was real whole food. Local if possible. We started making our own cheese and yog, so we bought a cow as a milk investment. I think a lot of the raw food recipes are brilliant for kids and beat the crap kids are given hands down. I don't deny treats, I just choose things like quality chocolate over a lolly. Something where you know the ingredients or we make it.
I think the raw food diets are interesting, but I think they can also be very expensive. A lot of the recipes cost a fortune to make for very little food. I haven't found it to be particularly economical - which sounds bizarre, but when you start looking at the individual elements that make up the diet and the things they suggest to cover all nutrients, it can end up being quite costly. As well as the different kitchen tools that people find valuable on these diets (juicer - a proper one that keeps in the fibre, thermomix, dehydrator) none essential, but valuable just to give the variety and different textures.

So all up, I think they are a good base, but I wouldn't limit a kid to something like this.
