This is one battle I chose from day one not to fight. Between 6mth to a year, I just started offering Spock whatever I was eating. She picked and played, she threw it away or tasted it and spat it back out. I just let her do her thing. She would have been close to 13-14 months before I would say she actually ate anything, we have just done the same thing, I would just make her a plate of what ever I have, often it is good variety, as a lot of our meals are random assortments of things. She still makes a mess sometimes, but more often than not she doesn't. She will try everything and if she doesn't like it she leaves it, and yes some nights she won't eat a single thing. But I just don't worry, the last thing I want to do is sit at the table for hours forcing her to eat, my personal view is by doing that I make food negitive leading to a variety of other issues. It's just a casual thing for us. If she then says she is hurry I reoffer the plate, and she might eat more... But I know she isn't staving or suffering from it.
She does graze and snack a lot though so she eats frequent little things rather than a big meal. So when I average it out over the day or week she is fine.
Please try not to stress about it. I think it just makes it worse for you.
