Birth weight is the single most important marker of
adverse perinatal and neonatal outcome.
Babies with a birth weight of less than 2,500g,
irrespective of their gestation are classified as low
birth weight babies.
These include both preterm and small-for-dates
Preterm infants (also called premature infants) are those
born before the beginning of 38th week of gestation.
Moderately preterm infants are those born between 32
and 36 completed weeks of gestation.
Late preterm infants fall in the moderately preterm
Very preterm infants are those born before 32
completed weeks of gestation. (Mehrban Singh, 2010)
About 10 to 12 percent of Indian babies are born
preterm ( less than 37 completed weeks) as
compared to 5 to 7 percent incidence in the west.
These infants are anatomically and functionally
immature and therefore their neonatal mortality is

premature baby in an upright position on a
mother’s bare chest allowing tummy to
tummy contact and placing the premature
baby in between the mother’s breasts.
The baby’s head is turned so that the ear is
above the parent’s heart.
Mothers have thermal synchrony with their baby.
The study also concluded that when the baby was
cold, the mother’s body temperature would increase
to warm the baby up and vice versa.
Kangaroo care allows easy access to the breast and
skin-to-skin contact increases milk let-down.
Increase weight gain
Kangaroo care allows the baby to fall into a deep
sleep which allows the baby to conserve energy for
more important things. Increased weight gain
means shorter hospital stay.
