QuestionMy sister in laws water broke at about AM is the baby or her in any danger and she isn't dilating?
AnswerIf her water broke, she will probably start having contractions within 24 hours. If she doesn't, her doctor or midwife will probably want to give her medication to start labor, although some midwives will recommend a national induction agent, such as castor oil. Her care provider will discuss those options with her if needed.
There is a small chance of infection after a woman's water breaks, which is why most doctors start labor artiicially after a certain amount of time (varies per dr or midwife) Some midwives do allow moms to go longer than 24 hours with careful monitoring for signs of infection. To lower the chance of infection, it is important to insert nothing vaginally, including limiting vaginal exams.
It looks like you are going to be an aunt very soon - congratulations! I hope her labor and birth go smoothly.
