Hi Cathie! Told you I was popping in here now and again!
Cranberries and blueberries are related, and neither are "true" berries. Not sure what they really "are" but I did some research on that one when I gave DS blueberries early on and then panicked that I wasn't supposed to give him berries and I had totally forgotten! Strawberries, raspberries, blackberries, etc are all a different food family. As you said, cranberries and blueberries are VERY uncommon as an allergen, BUT that said, you CAN be allergic to anything
OOO my friend is here 20 minutes early - will come back to this later this eve!
