Hi all, I've read about how the optimal sleeping position is on your left side as the vena cava rubs up your right, as does your liver. So I do appreciate then when getting bigger this extra strain on those areas isn't great. But just how important is it?? I've always slept on my right, and whilst I do attempt to sleep on my left since becoming pregnant, I always wake up on my back or right anyway. Does it really matter that much??? I could work myself up with anxiety over this!
