Completely agree with fussy eaters being born that way, although my definition of a fussy eater probably differs from the norm.
My son eats a list of 10 foods. NO fruit, no veg, no real meat, no sauces, no pastas or rice and the list goes on. We started him on purees when he was a baby and I send a fair share of the blame that way. He has always had quite a few quirks and issues with texture which is a huge roadblock when it comes to his eating. We've seen many doctors and tried everything we could possibly think of and research but we've had very little luck. I'm now refusing to stress out about it because he's happy, healthy, very intelligent and growing all the time so he must be going alright.

My DD on the other hand, we did BLS with her and she'll have a go at anything and everything. Sure, there are a few fruits and vegies she'd prefer not to eat, but at least she tries everything.

Food is fun until they are 1.
