Youngest ds is doing homework. It's a book review. He had to write about how he relates to the book. He has just said "the main character doesn't live with his family and neither do I." He has lived with us for years and is permanent. He was never freed for adoption and if he had been we probably would have. We had a lovely talk at tea last night about family, how we all have grown together and we now feel like a proper family. I know he struggles but it fair took my breath away. 
I will get over it too. Always do. Yesterday just felt like a huge step forward.
