I am 31 weeks pregnant with boy girl twins. Today the boy, baby a, measured 4.7 lbs, with 11.4 in fluid. The girl, baby b, measured 4.1 lbs, and 2.5 in fluid. My question is at what point does baby b's fluid level become a problem? Mfm didn't seem worried at all, but my doctor's partner said if it goes below two they have to take them. Also, a by the way, one week ago exactly baby b's fluid was 3.2

Sarah, your question here is way out of line. You are asking strangers this question regarding your pregnancy and it is not appropriate.

You have to ask your gyno these questions to get a proper viewpoint.
