I work in the medical field and I can tell you that you are not the first with such a plan. Grab a hanky folks. This is a true account of a story one of my familys told me.
One family I know of lost a child just hours after she was born. The baby had many health problems, but the mom wanted to deliver her full term and then send her to the angels because this child would never be able to live more than a few hours. And this mother did just that after carrying the child for 4 months knowing her fate was sealed. I have great respect for this mother. She has incredible strength. For the child's first birthday, last month, she took her hubby and her 3 adorable and totally healthy children to WDW as a surprise. Her husband thought that she had lost her mind, but she had a plan. On the birthday night she let them in on the plan. They went to MK and each got 2 balloons just before the fireworks. Just as the music started before the fireworks, they released one balloon and said a prayer sending the baby girl a balloon in thanks for having been even the briefest part of their family. They saw Tinkerbelle fly over and watched the fireworks and sang "Happy Birthday" to her. After the fireworks ended. They released the last balloons one by one with a wish for her to get her angel wings as her first birthday present since Tinkerbelle had spread pixie dust on them during the fireworks, they wanted to send it to the baby in hopes that it would help her get her wings.
I cried right there in the office like a baby myself when she told me. But, you could tell that it really brought the whole family a great deal of peace. So, I wish you and your family peace as you mark the anniversary of your own little angel's birth and passing. Love and Pixie Dust.
