June, I would use the salt reduced ready made stock. We all eat way too much salt as it is, so why not bring up the little one to be used to eating food without too much added salt?

I have also read that you have to be careful with home made playdough - make sure that kids don't eat it because the very high salt content can make them quite sick. I've even heard it said that it is safer for them to eat the commercial, chemical playdough (go figure!). Not that you woukd want to encourage playdough eating LOL, but little children often eat dirt (ours eats cat food if we're not careful!) so what can you do
