prayers please

Last week wednesday my SIL and her husband had an ultra sound, and it showed 2 perfect babies at 21 weeks. A boy and a girl. (they had 2 1sr tri miscarriages prior to this pregnancy) Then on sunday her water broke. Turns out it was the sac around the boy. He is strong and hanging on. The girl is doing well at this point. We hope these babies hang on for as long as they can and keep growing.
