Twins arriving at 34 weeks

Sally
I am booked in to have my twins on Friday when I'll be 34 weeks exactly. This is because I have too much amniotic fluid and increased bloodflow through the cords. I had steriod injections last week, and the babies were 4.5lbs on Tuesday when I was 32+4. So should easily be 5lbs easily by Friday. Anyone else's babies born at 34 weeks with a similar situation? How were they? Thanks
