Any ideas?

Any tips on how to get my 7 year old to try new foods? He is an extremely picky eater, he has some sensory issues, but is bored of the same stuff all the time. Do we just say you need to eat this or you'll go hungry? I feel awful when I don't just give into him but I know we're going to run into bigger issues if we don't sort this out. And we're in the process of trying to figure out what to do with sensory issues. His school just brushed the whole thing aside. He will be going to a different school next year though.

a reward system?

I've always said that my daughter has to have as many bites as her age. She's a good eater now. When she was 7 she had to take 7 bites
