I have a client that is nursing her nine month old infant. The
mother's periods had resumed, but they have now stopped. The obvious
answer would be a pregnancy, however, the baby has started to nurse
again every 2 hours during the night - would this increase in nursing
cause a delay in her periods when the baby is now 9 months old? We
thought that this might be the reason but we are looking for more
scientific data, to agree or dispute with our theory. She has no
other signs or symptoms of pregnancy.
