Sarah,
Congrats and enjoy that baby girl. She will remind you every day what a joy life is. Mine were some of my best care givers at 15 and 17, and I worried I wouldn't make it to the oldest' prom (month after diagnosis and weekend before surgery) and graduation celebrations (month after surgery). Now 19 and 21, they put up with all of their mom's hugs and kisses, then drive away. Yours is a captive audience for years to come! Congratulations and I am betting you will be an inspiration to your students as well.
Sincerely,
Lisa
