I'm pushing 26 Weeks pregnant with twins and at my last appointment the ultrasound lady told me both babies were head down facing back as apposed to the way they normally lay which was always the boy laying with his head under my ribs and feet down and the girl laying high horizontal at the top of my belly.. My doctor was very short with me but assured me my cervix was still closed but never said anything about the positioning, every time I'd bring it up he'd change the subject which was very odd.. Is it normal for the babies to get into that position so early? I feel them move towards the back and they're not as mobile but still move, does this mean they're ready to come now or do most babies get into this position normally around this time?

Since you are pregnant with twins it is possible that they get into position earlier than singletons do. However, it's still early and they may change position again.
