Hello all. I'm nearly 13 weeks pregnant with my second. Is this a myth that you can't sleep on your back whilst pregnant as it may affect the placenta?? I remember this being mentioned with DD1 but wanted to check with my fellow MNers. Thanks for answering my silly question
Its the blood vessels it pushes on. I'm struggling laying on my side, very uncomfortable, am much better on my back... Find that as long as I keep switching between my left, right and back, baby is active as ever, quite happily bopping around.
Apparently, if you lie on your back once you get bigger (I've heard various time frames inc 12 weeks, 24 weeks and 30 weeks!), the weight presses on the inferior vena cava, which is a major blood vessel that supplies mum and placenta.
It may well make you feel breathless and dizzy, so is best avoided.
Everything I've read said you only need to think about it from 20 weeks at earliest, and more like 25 weeks as LondonNinja says. Once you're bigger you'll probably find lying on your side more comfortable anyway.
Hi - I'm a back sleeper too and it has been frustrating having to stick to my side - have woken on more than one occasion in middle of the night, out of breath, to find myself on my back (I'm 32w). BUT some (random and prob fairly useless) advice: if you really can't help it, use an airbed! Just got back from a 10-day camping holiday and actually slept better on the airbed than I do at home - it's quite a deep one and was so cushioned it was like being on a waterbed, so I slept on my back every night and didn't get the usual symptoms (breathlessness, dizziness, which are def not a myth!). Also, as this is not a v. practical solution, you could always book yourself in for a couple of floatation sessions (if you have a centre anywhere near you) in the 2nd/3rd trimester as a treat? It's BLISS, takes all the weight off your back and if it works for you, you come out in a really serene state, like you've had a full night's sleep (impossible otherwise by the time you get to that stage!). Good luck!
