My sister had serious food issues with her son...
The only thing that worked was offering him his meal (after 8+ months of trying many different ways to get him to eat ind you!) & if he didnt eat or seem interested she would take it away, pop it in the fridge & take him out of his high chair & lethim go about whatever it was that he was doing...
Within a few weeks hedid start eating some food at dinner time, but he never starved & it didnt affect him at all that for months he rarely ate anything!!!
He now eats whatever is served up & tries new things & is generally a great eater! He is now almost 9!

so I say try to relax & not make it an issue coz they sense that & I guess it's a form of rebelling & so just say "Here's dinner, eat it up" If after 10 or 15 mins nothing is happening, remove the meal & let him go, coz working yourself up wont help at all..
Best of luck!!!
