[EX Q]: Do not buy this product.  You will not be doing your infant any favors.  If at all possible, you should be breastfeeding.  (I know it's not always easy or convenient.)  If you can't then in my opinion the best formula is Earth's Best and even that is disappointing.  Basically, they dry cow's milk and remove all the natural nutrients then "fortify" with synthetic vitamins/minerals.  Pathetic.  Just buy whole organic milk, raw if possible.  There are recipes online to make it closer to human breast milk.  Sorry to be so matter of fact.  I'm losing patience for all these evil corporations capitalizing on the "green" movement.  OH and by the way the second ingredient in this garbage is sugar!!! Good way to start the diabetes/obesity while they're young!

[EX Q]: We bought these chips at a little sandwich shop in Sonoma while we were on vacation. I wasn't sure what to expect by the package, and at first bite I didn't know what to think...and then all of the flavors hit! Yum! They are a bit spicy, but nothing overpowering. Just lots of crunchy, sweet, spicy goodness. They aren't sold everywhere though, I'm still trying to find them somewhere close to where I live.

[EX Q]: I just called up customer service and found that since October 2011, all the jars are BPA free. BUT...the jars manufactured before October,2011 are still available in the market. Usually all these products have a long shelf life as they are vacuum sealed. So the jars with BPA lining on the lids are still floating around in the market. The consumers cannot tell the difference. So what is the point in buying this when you do not know if you are giving your baby something that is BPA free or not??? This is very very disappointing from earth's best.
