Study: Baby spacing reduces risk of complications

December 16, 2009 New research in the journal Conception suggests waiting at least six months before getting pregnant again. But more than 11 months between babies could be even better.

The study found that when the interval between pregnancies was less than six months the chances of the baby dying, being born prematurely or having birth defects were much higher.

Why short intervals between births may cause problems is not known, but stress on the mother's body and hormones may play a role.
