I have been able to find it at a couple of local grocery stores, but not any big or small health food stores. I found that if the store carried any of the Looza brand but not the Pear Nectar, I could ask and they would get the Pear Nectar, too. And I also learned that if all of the Pear Nectar was gone, I would ask them at the front desk to order more rather than merely hoping that they would notice that it needed to be restocked.
Hang in there with the TED.
It can be a very effective tool in determining what foods bother your little one.
