Fussy eater - how do you deal with it?

[fluffyanimal]

DS2 is 2.4, and has steadily been getting fussier with his food. When under 2, he would happily try anything on my plate. As he got older, he refused more at home, but at nursery (I work full time) would still eat pretty much everything, so I have never been anxious about it as I figured that for 5 days a week at least, he would have a varied diet.

Now he has stopped eating his main meals at nursery. He'll eat his breakfast, his lunchtime desert and his tea. Basically, he is gradually coming round to existing on a diet of carbs, fruit and yogurt. At least at nursery they have baked beans or sardines on toast for tea, as well as sandwiches, scones etc.
At home he is terrible and will eat:
Toast
Dry cereal
Organix cereal bars
Crackers with butter or cream cheese
Yogurt
Baby fruit purees
Humzingers
he hardly ever eats fresh fruit for me, though he does at nursery.

If we go out he will eat:
Toast
Baked beans occasionally
Yorkshire pudding and gravy if in a pub
Chicken Korma and rice if in our local Indian
McDonalds chips.

He also drinks lots of milk.
In the main he is perfectly healthy and energetic, normal size and weight. I try not to make an issue of it. I always offer him some of whatever I've cooked, and I don't react when he refuses, I just take it away, and he has to wait until we have finished eating before I go and get him crackers or yogurt.
MIL is very supportive as SIL was also very fussy as a child, MIL dragged her round all kinds of doctors and health professionals to no avail and she is perfectly fine healthy and eats normally now, so MIL thinks I should just carry on, not stress and it will sort itself out with time.
Should I be trying to tackle it yet? Or wait till he is older and will respond a bit more to reason/rewards etc? Or just leave it?
My main worry is whether I should try to get him a vitamin supplement, just to make sure he is getting everything he needs. Sorry this is long, any shared experience will be most welcome.

Good advice from your MIL.
This seems to be an age where fussiness kicks in and your tactics seems quite sound - not making a fuss and keep offering - but not insisting on eating other foods.
His diet does seem a bit low on protein though. Will he eat cheese? Or any other meat than chicken korma (good choice though!)?
I think you can get some childrens chewable vitamins if you are concerned.
I have a fussy DSD (less fussy now than when she was little) and a moderately fussy veggie DD.

check out the incredibly fussy eaters thread...

Yes, there's a whole thread on this with lots of helpful tips and support.

Thank you both! Found the thread, it's in my Watch list now. Will read at leisure when I have more time, but already have mental note to try peanut butter and marmite.
But in answer to your question beamur, no he wont eat cheese - only cream cheese - or other meat. Until very recently he would eat roast chicken in gravy, but that seems to be going out the window too. As for the chicken korma, it's usually mostly the sauce. I can sometimes sneak the odd chicken lump in, but that often brings the eating to a halt!
Thank god for the weekly dose of sardines at the nursery.

will he eat mash? my DS has gone incredibly, um, chooooosy, and is 25m, doesn't seem bothered about eating at all at the moment, am hoping it will pass... my DS will eat mash made of potato, sweet potato and carrot mashed with butter and soft cheese, this is quite a good way to get some veg into him; peanut butter on toast usually gets scoffed, weetabix... um, I do a fruit milkshake as my DS like yours loves milk and won't eat any fruit except banana slices and occasional raisins, so I do a big cup of 3/4 fruit smoothie and 1/4 milk (innocent smoothies are great as they are pure fruit, mine likes the mixed berry one, the banana, passion fruit and mango one etc, also Asda's ones are 100% fruit as well and only a £1 a carton!), apparently a cup of that is 2 of your 5-a-day!

I've tried rice pudding as they're nice and rich but he won't have them, yours might though?

Mine loves pasta, so thats my saviour - he will eat lasagne, or I make a pasta shapes dish with tomato sauce (tinned tomatoes/garlic/diced onions+mushrooms/grated carrot/tomato puree/cheese) or cheese and garlic and mushrooms sauce, I made one the other day with shredded poached-in-milk salmon in the cheesy sauce and he ate the lot :)
