Re: canned tuna & strawberries (not together!)
I introduced strawberries at 8 months without problems. With the tuna, I'd be worried about the mercury content in the fish, and wouldn't feed it frequently to a little one.
It's good that people are buying dolphin safe tuna, but consider getting line caught tuna instead. The dolphin safe fishing uses a giant net that traps sea turtles, sharks, and other wild life. Line caught just catches the tuna, independent of other critters. It's much better for the environment.
