Megan Szylvian took to Parent Dish to share her letter with the world.
It read: "Today was supposed to be your due date. Instead, it is your three month birthday.
"You were born on a Thursday, after just 27 weeks of pregnancy. You spent the first 84 days of your life inside the sterile walls of an intensive care unit and I spent the first 84 nights of your life without you.
"I did a lot of praying in that time. Mostly I prayed, even begged, that you would not remember. I prayed that you would forget every injection; every procedure; every tube, lead and wire - and every minute spent alone in a warm plastic box.
"As I watched you grow, I began to realise that there are a few things about this nightmare that I don't want you to forget - a few things about yourself that I want you to know."
She then went on to remind her babies five very important things that they need to remember about themselves - and it's truly inspirational stuff.

There may come a time in your life when you feel weak or inadequate. Please remember what you were able to accomplish entirely of your own will and your own fortitude. You are strong.
There may come a time in your life when you feel like you are not ready for what is being asked of you. You may feel scared, overwhelmed or otherwise ill-prepared. Please know that your instincts about timing have always been correct. You are ready.
There may come a time in your life when you encounter those who do not share your many advantages in life. Never feel guilty about those advantages, but always feel grateful for them. You are privileged.
There may come a time in your life when you feel adrift or unsure of where to turn for help. Turn to each other. You are never alone.
For the lonely days, for the difficult days, my sweet boys: You are loved.
