I am glad to hear that you are enjoying your life in Hawaii, that your host family is so nice and that the food is good.
When I went to England to study English, the food was not to my taste . I had a hard time  for a month.So I am relieved.
Sora is 7 months old now. I am busy with childcare. But it reminds me of you and your brother's childhoods.
You are treasures for me.

Mom will always be considerate of your feelings and help you.
Mom will always be there for you.
If you are troubled I would tell you my ideas. But what I say is not always right. So it doesn't mean " Just do what I told you!" 
It means "Try to think it over and decide yourself"

I want to say again.
Happy birthday. I always wish you happiness. A year full of love.
