OP here---thanks! (And thanks, Google tracking...apparently Gerber Life is an option too...
I should have added that, like 14:47, we have the challenge of two parents whose costs are quite different (both healthy, but DH is early 40s while I am mid 30s), which apparently makes a big difference in costs). So that is really helpful info also! In our case, a 25-year plan (which only some places seem to offer) takes us through DH's retirement and a theoretical second kiddo's college years, but a 30-year plan gives us a little extra cushion in case college is not immediately paid off (likely!) and gets me close to retirement age.
