This is my 3rd pregnancy and all 5 Dr's I've ever seen say there is nothing you can do or not do that cause the babies cord to wrap around the neck... Certainly not sleeping on your back. Another old wives tale like lifting your arms above your head will do the same thing.. Nonsense.

My 2 doctors told me sleeping on my back can cause to warp the umbilical cord around the babies neck which got me so scared cuz for the first 17 weeks i was sleeping on my back. Now i am sleeping on my left side and rarely on the right side.

You definitely won't do any harm laying on your back! Listening to your body is the biggest thing.. If you start to feel lightheaded or dizzy, move to another position.
As baby grows, laying on your back can compress a major blood source and lower your blood pressure making you feel faint.

I did with my first. My doc said you’ll know if you shouldn’t be and you will.

I slept on my back a couple times around 36 weeks with my son last year nothing happened but I was told you can sleep however you want as long as you are comfortable and have no pain laying that way

Thanks Katie. Nikki it’s due to too much pressure on an artery I think.

Why are we not suppose to lay on our backs? ? serious question. I've never heard this before...

I lay on my back sometimes while Watching tv or a movie in bed. all depends on what feels comfortable for me at the moment. I think that should be fine. I'm always on my back when laying on the couch
