Baby B becoming "A"?

starlillee

I had a growth scan today and was surprised to find out that baby B had wriggled his way down further, pushing baby A out of the way and is now the twin that's presenting. (They are mo-di.) Both boys are doing great, at 1.3 lbs and 1.6 lbs and measuring right on track for 23 weeks.  Just curious if anyone else had twins that changed which one was presenting.  Did they change more than once before delivery?

Mine apparently did that. At my 18 week anatomy scan, Ryan was baby A and Nathan was baby B. By my next growth scan at 22 weeks, Nathan had muscled his way to being baby A. It stayed that way the remainder of my pregnancy.

Mine did. Miles was A first, until maybe 20 weeks? Then Linus pushed him out of the way, and they stayed that way til the end, I think.

mine changed as well.   once B nudged A out, they stayed that way.

Mine did that too!  Baby B remained Baby B throughout the hole pregnancy (even though about 1/2 way through he moved down)  then when he was born (since he was the first to come out) he automatically became Baby A.

Mine changed as well....I think it was later on in my pregnancy late 20 weeks and he stayed Baby B until he was born at which point he was Twin A or Baby A can't remember what their thing said....

if you have all boys (same gender), how do you know which is which???

I'm pretty sure ours "switched" too, but near the end of 1st/beg of 2nd tri, as our bigger baby b boy is now baby a and presenting. They haven't moved since. GL!

well, they still say on their own side of the uterus. miles was on my left, linus on my right, but one just had his head closer to my cervix.

Mine changed fairly frequently but, because of the growth issues I had we continued to call them Baby A and Baby B, they would just note which one was presenting.

hmm, okay that makes sense.  the problem with me is that my girls were transverse and at one u/s, they both had the same heart rate!!  so, when they did move (one is now presenting head down and the other is breech), i really dont know who is who.  i thought i was distinguishing them based on one being more active and i felt more kicks from baby b, but then an u/s tech told me that baby a was very active but that the position of her placenta might be keeping me from feeling her kicks and movements.  idk ...

Interesting! Mine never changed. A was always on my right, B on my left. (They were di/di.)
