Oh no. I am so so sorry. When I read that it gave me chills. I know you are heartbroken, my heart breaks for you. I pray my Abby girl lives that long. She is 4 now. What a great long life your Sidney had. Those babies give unconditional love and are so deserving of a good home.
God Bless You Sweetie and I will pray for your comfort. Just know that your baby is smiling down on you every day. I know that my DF and I have both said that when anything ever happens, we are getting another that day. There are so many out there that deserve a warm and loving home and lots who never experience that. You have so much love to give, I hope that in time, you will get another one and although that one will NEVER take Sidney's place, you know he will be looking down on you saying, "Way to go Mom!"
Big hugs from me and Abby...
