Been thinking about picky eaters again....

I have two children (many years apart). DS was the first-born - and when
he was a "toddler" we had little or no access to seafood or shellfish,
with the result that he never had much of either. To this day, he
dislikes anything remotely "fishy". He will eat almost anything else,
tho'. OTOH, our younger one (3 y/o) has been exposed to many kinds of
food, including seafood/shellfish and she seems to like it all.

I have noticed it with a quite a few of my friends - both with them and
their children as well - they seem to like what they grew up with and
are not all that keen to try anything that could be termed "strange food".

Anybody else think that if children are not "exposed" to certain foods,
say between the ages of 2 and 6 y/o, that they will never really
develop a taste for it, or that it will "take some doing" to get them to
try something "new" when they are adults?
