Text4Baby is supported by the U.S. Department of Health and Human Services and other partners. The messages have health tips for women who are pregnant and for those who are caring for a baby under age 1.
Dr. Juliette Kendrick of the U.S. Department of Health and Human Services said the text messages are timed to match the progress of a pregnancy or a baby's growth during the first year.
Kendrick said it is easy for moms to get involved.
