Many studies have shown that placing a baby younger than 1 year old
to sleep on his or her back is the most important thing parents can do to
reduce the risk of
sudden infant death syndrome (SIDS). SIDS rates
decreased significantly in most countries that adopted programs encouraging
this practise. Between 1990 and 2000 in Canada, death from SIDS dropped by
about 68%.1
Placing babies to sleep on their backs reduces the risk of SIDS. Side
sleeping was also recommended in the past, but it is much easier for babies to
roll to their stomachs from their sides than from their backs. Unless your
health professional advises otherwise, do not place your baby to sleep on his
or her side or stomach.
In rare cases, a doctor may recommend a different sleeping position
if your baby has certain health problems.
As babies mature, they learn to roll from their backs to their
stomachs. Babies who roll onto their stomachs during sleep do not need to be
continually shifted onto their backs. However, always initially place them to
sleep on their backs.
When your baby is awake and someone is watching, allow your baby to
spend some time on his or her stomach (“tummy time”). This is good for the
baby's development and may help prevent flat spots on the back part of the
head.
