I think made, but then maybe I have been lucky with DD (although she was a poor eater before 6 months and lost lots of weight, resulting in me giving up breastfeedinga fter a month).
Lots of my friends stress about their little one eating so much that they give in and give them the things they know they like. I think as someone else said, there is so much choice, and so much wealth nowadays that they don't 'need' to eat. And this applies to the parents too - we 'know' we can give them something else too.
I do sympathise with people who have picky kids, and I don't blame the parents directly - I think it is just a thing of our times really.
