I had a similar dilemma this year on picking between DODIX and VBMFX to add a considerable amount. I decided to go with DODIX because its bond holdings have a shorter duration (3.8 vs 4.79 according to Yahoo as of late last year). I'm guessing it's opting for shorter-term bonds in anticipation...

Completely agree with meadbh above, it took us 5 years before being blessed with our 1st kid. We didn't shell out too much for infertility treatments but I've learned from some couples who said they were spending amounts of a luxury car for it.
