Babies Need "Tummy Time"
Nearly 15 years ago, the American Academy of Pediatrics (AAP) first recommended that
parents put their babies to sleep on their back. That simple piece of advice cut the
death rate from sudden infant death syndrome (SIDS) 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 avoid 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 for a while.
This eases pressure on the back of the head and helps babies build shoulder and
neck strength. Interact with your baby during "tummy time" and provide objects for
your baby to see and touch.
Alternate which direction you place your child in the crib each night. Your child
will then alternate which direction he or she looks out of the crib.
Don't hang objects above your child's head. Put them on both sides of the
crib so he or she will turn his or her 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
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 he or she is lying down with pressure to the head.
If your child develops a flat spot on his or her head, see your healthcare
