How do narcotics affect unborn child?

Same as mom: Pretty much same way as they affect the mom, including potential for addiction after birth.

Caution: Usage of narcotics during pregnancy, unless under direct medical supervision and then only for highly specific indications, is not recommended. Narcotics affect unborn children and adults in the same way, although more profoundly, and with much more narrow margins of safety.

Depends: If you have to use low dose medication, or periodic medication no big deal. Recreational narcotics in pregnancy can have issues of w/d. If getting replacement, Suboxone or methadone, babies will have to withdraw but in a good environment seem to demonstrate no developmental issues. Need to know amount, what kind, etc to say how it will affect your pregnancy. Kind of a broad question. Gd luck.

See below: Narcotics do cross the placenta and so have an effect on the child. This can lead to somnolence and decreased respirations at birth (for recent ingestion) to a child that had a narcotic addiction at birth.

See below: Narcotics will cause respiratory depression and sedation.
