Just another hint if you are trying to get some vegies into him...DS pretty much loves to cook/bake and also likes all sorts of cakes etc cause they are sweet naturally. But I manage to grate peeled zucchini or mashed banana into a few baking items which he will then eat with relish without realising. Some ideas are:

Zucchini pikelets
Banana pikelets (atm am adding a tiny bit of crushed chocolate from all of our leftover e.eggs)
Banana and chocolate (as above) cake or bread
Scrambled eggs with purree cauli
Choc/zucchini cake
Banana and zucchini cake
Ham and cheese mini muffins with zucchini

Zucchini is tasteless and flavourless and if you grate it finely enough they never know. A bit sneaky I know but it at least eases my conscience at times.
