No: Try to sleep on your left side, it will keep pressure off your aorta and provide better blood supply to the babies. All the best and I hope all goes well.

I suggest you place one of those long "body pillows" behind your back. Right now your sleep position isn't important, but, as the babies get larger, you're right that sleeping on your side is best (in part you breathe better!) I think Dr. Cox meant that sleeping on you left side takes pressure off the main vein (vena cava). The aorta is under higher pressure & won't get squished.

No: You are basically a protective environment for baby.Babies placenta extracts the proper nutrients, and you just carry the fetal-placental unit around. The sometimes concerning symptoms you may have will generally not effect baby. The exception would be changes in your blood pressure, dehydration, significant illness, etc..These things change the "environment" for baby.
