I want to try our DS on fish oil. I know I saw discussions here a long time ago about what specific omegas to look for and how much to give daily. Can someone remind me what those were? Also, what brand/type should I get? He can swallow pills but I don't think he'll be able to do those huge horse pills that fish oil tabs come in. Should I do kids' chewables or get a liquid? Any brand that kids like? I don't need any more things to fight about with him!
