Birthday before a Birth-day

I've heard that 30 is the new 20. I've heard people are much more sure of themselves at 30. I've heard that 10 x 3 = 30.

I remember thinking that I wanted to have my first kid by 30....and being a scientist, I know that everything has a degree of uncertainty, so we'll say that 30 +/- 3 weeks is pretty much 30.

I know that after this point, almost everything will be about the future baby Niles, so I will now say buh-bye to my childhood and look towards the new childhood about to start!
