Nuchal cord I know is common, and rarely results in problems with the baby. Cord accidents are very rare, and risk of infant death is only .4-.6% chance of happening. Something like 25% of births are babies that have the cord around their neck, and over half resolve themselves before birth. It won't suffocate the baby per say, because they don't breath in their mouth, but rather through the cord and it's rarely tight enough to cut off the oxygen flow.
Thank you soo much. I will be more relaxed know that I know that........
Good luck with the rest of your pregnancy!
