I can understand your partner’s concern for the baby, as there is
a lot of public awareness around bacteria and germs and we are
constantly bombarded by the media with information on germ-fighting
products such as disinfectants and bleach solutions. However, if we
create too sterile an environment, we are also killing good bacteria
that can actually help us. Also, exposure to microbes and getting
infected with some of them strengthens the body’s natural immune system
against allergies. An immune system that has little exposure to germs is
more likely to see dust and pollen as dangerous invaders and respond in
a way that causes asthma and allergies.
Babies begin preparing
for the germs they will encounter at birth while still in the uterus
since, although the placenta acts as a filter, it lets through small
amounts of allergens and microbes. It is thought that by three years, a
child’s body has learned all it needs to know to fight against germs.
However, it is advisable to try to keep newborn babies away from people
who have colds, since very young babies have difficulty breathing
through their mouths, so if they have mucus in their nose this will make
them very snuffly. Breast-feeding provides babies with some immunity
from infections.
Babies will continue
to come into contact with germs despite parents’ best efforts to avoid
them, and it is not really possible or desirable to live in a germ-free
world. So try to reassure your partner that even though your sister may
not be fussy about housekeeping, a visit to her home is unlikely to harm
the baby. One exception, though, is hand washing, which is of paramount
importance. Most infections are spread through the hands, since most
people do not have a very good hand-washing technique. Before caring for
a newborn, preparing bottles, or preparing any food, it is important to
wash your hands thoroughly.
