Lynn,
I am so sorry for the pain you are feeling and the terrible loss of Cooper.
This time of year makes things all the more painful.
Cord accidents are very rare but sadly they do happen. The chances of this happening again are so very very slim my love... That is no consolation now but just in answer to your question.
Please lean on all of the wonderful women in here. Sadly many of us know some of the pain you are feeling. You will survive this horrible time. Always will you hold Cooper in your heart but this terrible raw grief in time fades to a pain more manageable.
I am sending you lots of love and hugs...
