This is a tough one for me! I have a similar post with my GLW that everyone says is roo. I just posted up more photos. I'd be interested in seeing how yours ages. To me...he looks like a younger version of mine, but whaddoIknow?
I'm in the same boat and it appears nobody wants to take a chance on guessing the sex of mine. How old is this GLW? It looks to be about the same age as mine, 6 weeks?
I guess I'll find out soon enough.
