I am sorry that I haven’t written this letter before now. It has taken me three years to gather the courage. I have started it so many times in my head, but was afraid that you would think it disrespectful of me to write to you. It does seem strange writing to someone I have never met, but part of me feels that I know you very, very well.

We read your file one morning in September. We knew the contents would be difficult. Later that afternoon, we received the call from our social worker to tell us that you had passed away. Suddenly, we knew what we had to do.

There was never any doubt. All I remember was an a desire to protect this little boy, to give him the love and care he deserved. And really that was that; as far as we were concerned, David was now our son. There were further meetings, questions, paperwork, decisions, arrangements and preparations. Then, two months later, we met him for the first time. I hope the fact that I call him “our son” does not offend you. Sarah, you will always be his birth mother. But I make no apology in referring to him as our son.

For the past three years, we have loved and cared for David. We have dealt with his anger, his confusion and his anxieties. David was taken away from you soon after his second birthday. I cannot imagine the pain that must have caused you. We know that you really wanted to be a good mother to David, but you could not cope when his father left.

It is tragic that your life ended so early. I don’t know how I will explain all these things to David as he grows up, or how he will explain his story and what happened to him during his early years. I hope that it does not cast a shadow over his life as his understanding deepens. I hope you can find comfort in the fact that, from all this pain, Sarah, you have given us the most wonderful gift – an amazing little boy who is completely fearless.

It is so unfair that you did not receive the love and the warmth in your childhood that David now takes for granted. And although you never chose to hand your beautiful baby over, I can only feel gratitude towards you for this wonderful little boy who has made our lives complete.
