Is there any type of fish I'm not supposed to feed my 9 month old yet?

Avoid giving fishes with high mercury level for babies. Fishes that consist high mercury level would be ' Batang, Tuna" Try giving Deep Sea Fishes or Fishes with high omega fat which is good for their brain and eye development. I purposely give Threadfin fish to my kids. Salmon is a great alternative too. http://wholesomebabyfood.momtastic.com/introducingfishtobaby.htm
