My 30yo BIL still picks out all the veges in his meals. :/ Not sure what my point is.. just saying for shock value I suppose.
I imagine I'll be doing the same at 30. I haven't willingly eaten most vegetables since I was a toddler. I eat potatoes and onions, that's it. The onions are a very recent addition.

I agree with everyone saying don't make a big deal. Mealtimes were always tense if my dad and I were eating together - he'd try to force me to eat things I don't like, right up to when I moved out of home. He still does it with my youngest brother. I doubt I'd be eating veggies if he hadn't anyway, but why make things tense and upset your kids for no reason? My mum never had a problem just leaving a couple of different things off my plate and giving me a little extra of what I did like.
