oh how horrible is that her dh not seeing her?
maybe you can call the hosp and be puh through and have a chat to her.
i went into hosp at 32weeks with my waters leaking and on strict bed rest it was sooooo boring so even a ph call may do her the world of good.
maybe tell her how you have done some research on whats happened and put a positive spin on it?
its true each day she can hang on baby will benefit, but there is a high chance she wont make it to 37weeks +.
i was told i could go into labour over night or last up to 4 weeks. i lasted 5days which i know beneifted my baby.

as Sally said your body keeps replemishing the fluid so if she avoids infection she could really get a lot further down the track. in saying that i am sure she wont be coming home from hosp until bub is born.

let us know how she is doing
