The researchers included Angela Underdown, MSc, associate professor at the Institute of Education at England's University of Warwick.
They reviewed 23 studies on infant massage, mainly in newborns.
The reviewers note "some evidence of benefits on mother-infant interaction, sleeping and crying, and on hormones influencing stress levels" in massaged babies.
For instance, massaged babies had lower urine levels of certain stress hormones than babies that didn't get massage.
The studies varied in length and massage style. So it's not clear what type of baby massage or how many sessions work best.
Baby massage didn't affect infant growth and didn't appear harmful, the reviewers note.
Underdown and colleagues say their findings support infant massage, but they aren't ready to recommend massage for all babies.
The reviewers call for more studies on infant massage. Meanwhile, if you're interested in massage for your baby, talk to your doctor.
