Last month I noted the launch of the Text4Baby SMS service to educate moms and moms-to-be with skepticism:

As a pediatrician I am pretty strongly committed to the health of moms and babies, but to me this program is exactly what we don't need: an million-dollar custom-built system to send text messages on one particular topic.

So the U.S. Chief Technology Officer today announced a "free mobile health service for pregnant women and new mothers."  The system, text4baby, allows moms to receive text messages about baby health on their phones.
