Keeping Your Baby Warm
Babies can't adjust to temperature changes as well as adults. Babies can lose heat
rapidly, nearly 4 times faster than an adult. Premature and low-birthweight babies don't
have much body fat. Their bodies may not be ready to control their own temperature,
even in a warm environment. Even full-term and healthy newborns may not be able to keep
their body warm if the environment is too cold.
When your baby gets too cold, he or she uses energy and oxygen to generate warmth.
If his or her skin temperatures drops just 1 degree from the ideal 97.7° F (36.5°C), your
baby's oxygen use can increase by 10%. Keeping your baby at a temperature, which is
neither too hot nor too cold, helps him or her hold onto that energy and build up
reserves. This is even more important if your baby is sick or premature.
Ways to keep babies warm
Ways to keep your babies warm are:
-
Drying and warming your baby right after birth. Wet skin can cause your baby to lose heat quickly by evaporation. He or she can quickly
lose 2° to 3°F. It is important to warm and dry your baby right away using warm blankets
and skin-to-skin contact. Another source of warmth such as a heat lamp or over-bed
warmer, may also be used.
-
Open bed with radiant warmer. An open bed with radiant warmer is open to the room air and has a radiant warmer above.
A temperature probe on the baby connects to the warmer. This tells the warmer what
your baby's temperature is so it can adjust automatically. When the baby is cool,
the heat increases. Open beds are often used in the delivery room for rapid warming.
They are also used right away in the NICU and for sick babies who need constant attention
and care.
-
Incubator/isolette. Incubators are walled plastic boxes with a heating system to circulate warmth.
Babies will usually start out dressed only in a diaper while the heat is fully on.
As the heat level is gradually reduced, more clothing is added. Once your baby is
stable and can maintain his or her own body temperature without added heat, he or
she is placed in an open crib or bassinet. Your baby will likely be dressed in a gown
or T-shirt, a diaper, and possibly a hat. Often, a blanket or sleep sack is wrapped
securely around the baby. This is called swaddling.
To lower the risk for sudden infant death syndrome (SIDS), the American Academy of
Pediatrics advises that parents and caregivers not overbundle, overdress, or cover
an infant's face or head. This is to prevent your baby from getting overheated. In
addition, there should be no extra blankets or toys in the bed because they could
block the baby's breathing.
