I might be going off on a bit of a tangent here, but I have managed to get my fussy 2.5 year old to add quite a few vegies to her diet by the following method:
First night - I tell her she must pick it up and lick it
Next night - Take a tiny nibble
Night after that - small bite
If she spits it out I don't worry, I just keep going. Sometimes I need to spend several nights on the same step. I am amazed how well this has worked actually! She now likes lots of things.
I don't know if it would work for your little one, but I just thought I'd suggest it just in case.
