From weaning to aged 1 both would eat anything.
Now 3.9yrs & 2yrs will eat (when they feels like it not every portion at every meal) sweetcorn, peas, broccoli, carrots (cooked or uncooked) , tomatoes, olives, cucumber, swede.
Don't forget that a small tin of spaghetti in tomatoe sauce is 1 of their 5 a day, same for baked beans.
Mine will eat pretty much any fruit so I make sure they have berries every day, banana, fruity yoghurt, fruit juice, yoghurt coated raisins, apples, plums, pineapple etc. I think as long as they eat a good variety of fruit they will get their vitamins & minerals that way.
I explain to DS1 that blueberries are a Super Fruit (although I think it's Super Food?) and they will give him super powers, ha ha, he is really into super heroes at the moment. Same with carrots, I say they will give him super eyesight.
