Umm yip, they're inseperable. Not sure how healthy this is, but we don't make any particular effort to keep them together nor seperate them. I hope just leaving them to develop without interference is the best choice.
This is my 8 year old daughter Aislinn. I think she might be an alien. The first two pics are from a camping trip we took to Bankhead National Forest, the last one is from the renaissance faire in Florence, AL.
