Hi all,
I am having a issue. I have my first child due in 8 weeks or so and am wanting to obviously take as many photos as I can. I am also moving into taking more people shots, portraits and group shots. I am considering adding a lens with better low light capabilities...or should I be getting a flash. My current considerations are Sigma 30 1.4, EF-S 60 2.8 macro or a 430 EX.
What does evey one think?
Budget is somewhat limited so I can probably only convince the treasurer to let me have 1 

buy what you need to get it off the camera - light stand, bracket, umbrella or softbox (depending on funds) and Ettl sync cable. Will improve your pictures way more than another lens.
