Firstly, let mummy apologise for not writing this letter any earlier. I wanted to get this done before your 4th birthday. By now, you would have known that mummy has gone through quite a little bit of drama to get you a sibling over the month of May. Hence, this came only now.
I am sorry at this point, mummy and papa will not be able to promise that you will have a brother or sister. That said, we want you to know we will never stop loving you. And, no amount of drama we went through would make us love you any less.
