Can anyone tell me if it is possible for a 2.9yr old to eat too much fish?My dgs has it up to 4 times a week eg salmon and broccoli with pasta,baked cod with veg and herbs,haddock in a cheese sauce with veg etc.He had been ill recently and every day he asked for salmon-he didnt get it of course.He eats very little meat except in pasta sauce and the very occasional sausage.Does this sound ok?The other days he has veggie things-loves pesto and spag with tomato etc.
