Admitted to hospital

Mitch and I went to our maternal fetal medicine specialist on September 29th.  The appointment went very well and baby B looks to be doing very well.  The doctor did an internal ultrasounds and found my cervix was at a 2 when it should have been at a 4.  Baby A's membrane was starting to funnel out to the cervix.  I was sent to Via Christi St. Joe to be given steroid shots to help develop baby B's organs and magnesium sulfate to calm any uterine activity.  The magnesium sulfate makes me have double vision and feel pretty woozy so its not too fun to try to read a book or do anything on the computer.  I did want to give everyone a quick update.  I will be in the hospital until Saturday afternoon when they will reevaluate how things have progressed.  Best case scenario is I go home and am on bed rest.  Worst case scenario is I stay in the hospital for the remainder of the pregnancy. 
We met with a NICU doctor when we were admitted to go over any questions and what to expect for complications with babies born so early.  The survival rate is fairly good - around 85% and it increase with each day.  The biggest risk is bleeding in the brain.  Right now they have 24 weeks twins and a 25 week baby and they are all doing well.  He made us feel pretty comfortable with the fact our baby will be well taken care of.  The best thing of course is to have the baby stay put for as long as possible.
We would appreciate any prayers you could send up.  Thank you to everyone who is thinking and praying for us.
