Hey, he ate the broccoli shapes (what are those, btw?)! Would he have eaten the chicken nuggets if they were what you normally served?
I think it's great that you're keeping the "rule" consistent. It feels like you're banging your head against the wall, huh? Having to keep reminding them? But eventually, he'll try something, like it, and will realize that some new foods ARE really yummy (erm, sometimes, but that's life
). We're still trying to keep with the consistency, too. It's hard not to backtrack and give them anything when you know they'll be hungry...but I think you're doing the right thing.
