Organic?

It's up to you.  I made all my own puree's with organic fruits and veggies.  I prefer organic mostly just because they taste better  :)

Look up the dirty dozen for fruits/veggies, I would at least use organic for those choices when making baby food:)

 I buy from the local farmer's market : )

It's up to you.  You could look up the fruit/veggies that have the most pesticides used on them and buy organic for those.  I think strawberries and bell peppers are two that require a lot of pesticides.  I don't buy organic in general, but lean toward buying for certain organic foods at times.

Well of course organic naturally are better because they don't have any chemicals sprayed on them, however there haven't been any studies showing that there is any health difference between the two.

Au contraire! There are many studies showing that children have lots of chemicals in their blood due to exposure from nonorganic foods. I would never give a baby nonorganics.

Its just what we all use. We have our own garden. I personally think it tastes better and there are not any chemicals on them. We also get fresh eggs and meat from a friend.
