There are a few situations in which breastfeeding might not be possible
or medically advisable. Examples are:
- Maternal death,
- Maternal HIV infection (in some situations),
- Maternal use of illicit drugs.
Maternal death related to childbirth is very rare in the developed world.
Most infants whose mothers die in the developed world are
fed a breast milk substitute and do very well.
In the developing world the risk of infant death is very
high when fed a breast milk substitute. In many countries, an effort is
made to find a wet nurse for the baby.
