"Jordan is my rainbow baby 🌈. After the loss of my child I didn't think I could go on, but then I found out I was having a baby and I knew she was going to be someone worth sticking around for.

I miss eldest child every day, but her rainbow baby sister carries on her name and we live on to make her proud."
