Moving a low-lying placenta? What?

I was just on another site, and came across a thread about what people prefer in birth (Caesars or vaginal birth) and came across this exchange:

I want to give birth naturally. I have a low lying placenta at the moment but I'm hoping that will move, otherwise it could mean a c-section.

Right under that was someone else:

I am the same as {first poster}, low lying placenta which i am praying will move. hoping bub will kick it out of the way :)

I'm a little concerned, maybe it's the way they worded it and I'm reading it wrong, but it seems to me that they think the placenta is able to move from the position it's stuck in. I'm sure this can't happen, because it's... Well, stuck. Right? I'm not really sure what I expect to come from me posting this, to be honest, I guess I wanted to share. Get some other thoughts on it so I'm either justified in wanting to correct them, or have my mind set at ease so I don't want to anymore :p

As always, I've had another nonsensical rambling post :lol:

I think it's just as the uterus grows the placenta moves up with it, so it's position to the cervix can change. So it can "move".. but not from where it's attached, just relative to the cervix.

Did that make sense?

Oh yeah, that's kinda what I thought just after I posted... Thanks :) Even if that's not what they meant, if I make myself believe that I can stop myself from going back to correct 'em :p

hehe so hard to not correct people sometimes!
For what its worth i had a low lying placenta with DD and it "moved" toward the end of the pregnancy.
Liz is right!! the placenta doesnt move but it has moved in relation to your cervix!!

Yep the placenta itself does not move. It's attached where it's attached. As the pregnancy goes on and your uterus grows bigger, the placenta moves with it 95% of the time. Imagine if you have a balloon and put a texta mark near the top of the balloon where you blow, then blow it up, you'll see the texta mark move further away. Hope that makes sense!

I just hope we're right in thinking that's what they meant, I'd hate for them both to be waiting for their babies to "kick it out of the way" like it was just floating around in there (that's the image I had in my head when I read the posts) :p
