Kia, I'm so very sorry for your loss. Thankfully, I don't have first-hand experience, but I've often heard that losing a child is the absolute worst pain a woman can experience. You're in my prayers, especially on the anniversary of Baby Oliver's passing.
I'm afraid I can't actually release a balloon for you, as there's no place here that sells helium balloons. I live on an extremely small island in the middle of the Pacific, and resources are sometimes difficult to come by. I've also heard that balloons aren't too healthy for sea turtles, and we have lots of them here. Don't know for sure if it's true, though, could be an urban myth.
Anyway, blessings and prayers for you!
