You are only five years old and I cannot expect you to understand the complex developmental barriers that keep your Big Sister from speaking with you, playing with you, and doing big-sisterly things with you.
One day, I am sure I will be able to explain autism to you and your younger three-year-old sister, Joy.
One day, both of you will be able to understand and accept why your 姐姐 sometimes grabs your toys or food without asking, making you cry.
One day, both of you will be able to understand and accept why your 姐姐 likes to sit at the corner, lost in her own world, playing with her plastic bag and giggling to herself.
One day, both of you will be able to understand and accept why your 姐姐 needs to have her hand held in public places, while we let you walk by our side on your own.
But today, you made your Papa very proud when I told you to help Big Sister put on her shoes, and you did it willingly and without question.
It gives us, your parents, hope that Faith will grow up surrounded by the love of her siblings, long after we are gone.
With lots of love,
P.S. This does not mean the "No crying in shopping centres when Mommy does not buy you the toy you wanted" rule has been changed. And Joy, if you are reading this, the rule applies to you too.
