My son is getting ready to start baby foods. Which brands are the best for him? Is one really better than the other? I have read that some have additives. What should I look for? I am considering making some periodically but would not be able to make all of his food. Which is better - Earths Best or Tender Harvest? Or are these organic brands any better than say Gerber, Beechnut or Heinz? Thank you for your input.
