You can't prevent every cold, but there are things you can do to
minimize your baby's exposure and boost her defenses.
For starters,
make sure family members and friends wash their hands before picking
up your baby (this is particularly important with newborns, who are
more susceptible to illness than even 1- or 2-month-old babies). To
the extent you can, keep your baby away from sick children or adults;
they will understand if you ask them to postpone a visit until they're
not contagious.
Keep in mind that babies in daycare get more colds
than those kept at home simply because they're exposed to more kids
and, hence, more illness.
Make sure your childcare provider is
conscientious about washing her hands.
