Saturn is our Karmic Teacher--it sets limits- gives rules. Being in the 12th will restrict your own self undoing- the little one will help keep you out of trouble

(Saturn is in its Joy in the 12th) Yes, I agree that you both can affect people in similar ways and if your Husbands Mercury is involved he will try to express this so maybee he will talk alot about this very detail or simply about the both of you, yet in the 12th you would rather keep it personal business? Jupiter also being there Jupiter relating to
E X P A NSIVENESS, so its an emphasis as well. Is this a big baby? Saturn and Saturn together both being responsible for each other, even this little one may end up wanting to be responsible for you though time. Mercury is communication and thought process, I am thinking that you and the little one are responsible as well to your husband not to be overbearing -Saturn is the conductor while his Mercury is expressing that very energy.
Just a train of thought on this--and you have gotten me reading my new book that just came in today its called Discovering your Soul mission How to use Karmic astrology to create the life you want-- by Linda Brady and Evan St. Lifer so thanks to you as well.
