Baby Shower Congratulations Cards

My biology teacher waiting for a baby girl in September and classes are throwing a baby shower at school. We each get a present and so on. I have a gift and a card, but do not know what to write in the card other than "Congratulations" and "Best wishes. Suggestions?

thats really nice of your class! Simply put there you will make a great mother. It'll make her happy and give some confidence to be the best mom

You will be a great mom

She is ACE's biology class ... ETC.

Having a teacher for a mother who will be great ...

Congratulations on your new bio-mass! I know you'll be a great mom! XD
