Babies Need "Tummy Time"
Nearly 30 years ago, the American Academy of Pediatrics first recommended that parents
put their babies to sleep on their back. That simple piece of advice cut the death
rate from SIDS (sudden infant death syndrome) by more than half. An unexpected result
has happened, however: flattened heads.
The flattening—a result of babies' spending so much time on their back—most often
happens on the back of the infant's head and is usually more noticeable on one side.
This flattening may broaden the head and face. In severe cases, the flattening may
push forward one side of the face. This creates an uneven appearance.
No one's sure how common flat heads are. But around half of infants have some amount
of flattening of the head by 2 months of age. Only about 1 in 5 of those have severe
changes, according to a 2013 article in the journal Pediatrics.
To prevent a flat head—medically known as deformational plagiocephaly or positional
plagiocephaly—try these tips:
Parents should still place babies on their back for sleep.
When babies are awake and under supervision, put them on their tummy. This eases pressure
on the back of the head and helps babies build shoulder and neck strength. Place your
baby in tummy time while awake and supervised for short periods of time. Begin this
soon after hospital discharge. Gradually increase tummy time to at least 15 to 30
min total each day by age 7 weeks.
Interact with your baby during "tummy time" and provide objects for your baby to see
Alternate which direction you place your child in the crib each night. Your child
will then alternate which direction they look out of the crib.
Don't hang objects above your child's head. Put objects on both sides of the crib
so they will turn their head to look at them.
Dress your child in clothes that allow for freedom of movement.
Alternate sides if you bottle-feed your child. Don't let your baby fall asleep while
bottle-feeding. Milk or formula pooled in your baby's mouth can cause tooth decay.
Reduce the use of car seats when not traveling in the car, as well as other types
of seats, like bouncers, in which babies are positioned on their backs.
Pick up your child often. The more time your child is held in your arms, the less
time they are lying down with pressure to the head.
If your child develops a flat spot on their head, see your healthcare provider.
