Thanks, lindasu. I thought that's what I've heard/read. You mentioned you top your oil with a piece of plastic wrap - that makes good sense to keep the mold off, but doesn't it also trap in the bubbles? Or is letting them out once a day OK?
I went to the field and picked my GR - 3yo DS came with me and had a ball, running down the path, running through the grass/weeds and occasionally picking a flower to bring back to me.
I also have some more flowers to identify! What fun!
After reading this thread and checking out some pics on the web, I now know what ragweed is. (It was a 'so THAT's what that is!' moment!
) I've pulled plenty of it out from around flowers never knowing what it was, and since I don't suffer from allergies I've never bothered to look it up before.
