24w6d my water broke. 25w1d doctor confirmed there not much fluid left, and told me they monitor. how long baby can stand without fluid?

Quite a while: Remarkably, many women in your situation will be managed to deliver after 33 wks. Even if there is not much fluid, the risk to the baby is greater to be delivered early (at 25 wks) than it is to stay without much fluid. You can talk to your doctor about a transfusion of amniotic fluid, but the evidence for that changing outcomes is uncertain.

See below: The fluid round the baby has the lungs develop and helps cushion the baby so babies who live in little fluid can have issues. If you continue to stay pregnant and not go into labor they would induce you at 33-34 weeks. You should be closely monitored for signs of infection. Report any fever, chills or increase in abdominal tenderness. Good luck. Prayers for you and your baby.
