Improved sleep—for both your baby and you—might be just a touch away. Recent research indicates that giving infants massages may help them sleep better, cry less and feel less stressed. Researchers from the University of Warwick in England reviewing nine studies about children who received massages discovered a range of significant results including a decrease in the stress hormone cortisol and a link to the release of melatonin, which aids infant sleep patterns, says lead study author Angela Underdown, an associate professor at the university's Institute of Education. Massaging your baby can help you relax, too—perfect when reconnecting after a long day's work, so ask your pediatrician about where to find baby-massage classes.
