Congrats to your sister. How did the pregnancy test go?
Sorry to hear that you lost your mum at a tender age.
It is very thoughtful and caring of you to put up this thread for your sister.
My advice for 1st time mummy will be:
Do rest well, stay happy and positive, eat a balanced diet and eat in moderation, do some light excercise if your gynae says ok, engage your hubby in pregnancy and parenting classes and avoid medications esp. in the 1st trimester and inform the doctors that you are pregnant before taking any medication.
Why not invite your sister to join as a forum member here and she can ask questions and get the answers directly? ;-D
