Baby food mill
This baby food mill seems to work very well. My SIL used it for both her kids (same concept, but a different brand, I think). It just grinds up whatever everyone else is eating and then you feed the child right from the mill, so no extra dishes to wash. She only had one but I'd have a couple if it was me, so in case one was dirty the other would be ready to go. These travel well in the diaper bag, too.
If you're familiar with ricers, that's pretty much what this device does but in a neater, more convenient fashion. The hand crank eliminates any need for electricity or batteries, so it's great for camping or anywhere.
