And I'm still standing still . . .

The wife of a colleague of mine just gave birth to their second child in less than a year and a half. I remember when their first daughter was borne, we'd only been trying for 6 mos. (Feb. 2004) and I assumed it would be just a matter of time before I'd be sharing our good news. Well here we are, it's June 2005, she's delivered number two and I'm still in the starting blocks. I know that I should just feel happy for them (and to a certain extent, I do) but I can't help the feeling that I am making no progress and that time is just passing me by . . .
