This way, by your third trimester or certainly by the time of the delivery both you and the baby are clean
and ready to start healthy bonding
and nursing.
The OB/midwife will also be there to guide you though good pre-natal care, healthy nutrition, smoking cessation (if necessary), etc..
Good luck to you, motherhood is a career full of joys and pain, but we all do it for the joy of it...
