Could somebody chek my writing task? please

Task : Your cousin, who lives abroad, has recently written you a letter. In it, she asked you to tell her all the family news she has missed. Write a letter, telling her what she wants to know. (Write a letter of between 120 and 180 words in an appropriate style.)
Dear Tina.
It was great to hear from you. Hope everything is fine.
You asked me to tell you all the family news you have missed. Well, a lot of things have happened since you had left. The big news is or cousin Svetlana is pregnant. She is going to be a mother for the third time. We all are very happy for her and her husband. They told us that they are expecting the baby at the family supper last Sunday. The Grandmamma was moved to tears.
Oh, and another thing! Do you remember the Fluffy, the cat? We can`t find her anywhere, despite looking all week. We have no idea where she`s gone. It is really sad. We all miss her and hope she will back soon.
We all miss you too. Will you come to see as in the summer holidays? Hope you do.
Everybody sends their love.
A.

[Very good.  I changed the order in the one sentence because it implied that they were expecting to have the baby at the supper last Sunday.  The new order says that Sunday is when they told everyone.  It is a mistake that many native speakers make.]
