Thanks MR, Karl said the same thing re being advanced for his age and being creative about coping with stress - that it's a good thing.

Schaz it's funny that you say that. My mother believes in spirits (as Asians tend to do, despite being devoutly Catholic) and she firmly believes it is the spirit of his 'twin' - the other embryo that was transferred with him that did not take. I too have my thoughts about spirits so am open to the idea, whether or not it is the other embryo, and have no issues with it if it is the case.
