Am. Walker et S. Menahem, INTERVENTION OF SUPPLEMENTARY CARRYING ON NORMAL BABY CRYING PATTERNS- A RANDOMIZED STUDY, Journal of developmental and behavioral pediatrics, 15(3), 1994, pp. 174-178
The role of supplementary carrying of infants was studied. Normal babi
es were randomly assigned to an intervention or control group. Infants
in the former group were carried by their mothers in a soft ventral b
aby sling for at least 2 hours a day. The crying and behavior patterns
of individuals in each group were documented in a 24-hour diary at 1,
2, 4, 6, and 8 weeks of age. Twenty-two infants were enrolled in the
intervention group and 21 in the control group. Little difference was
noted between the two; indeed, those carried in the sling appeared to
have an increase in the duration of fussiness. Crying behavior mostly
occurred between 4 and 8 p.m. each day, with an additional peak betwee
n 8 a.m. and noon noted in the control infants. The latter peak disapp
eared by 4 weeks of age. Although other benefits may ensue from carryi
ng the infant, its use in decreasing crying and fussiness has not been
demonstrated.
