Dear [recipient's name]:
Wow, I was just so thrilled to hear the extremely joyful news about the birth of your happy, healthy new baby daughter! Congratulations! I know both of you will be excellent parents, and I hope and pray your daughter has a really healthy, happy life. I look forward to getting more details about baby Elizabeth, and to of course seeing photos of the adorable little one, whenever you get the chance to contact me.
Meantime, please do not hesitate to let me know if there's anything I can do to help you in the busy days and weeks ahead. I would be glad to bring meals, help with housework, run errands, or pitch in any other way.
Happy congratulations to all of your family! I'll see you very soon and cannot wait to meet and hold little Elizabeth.
Sincerely,
[Signature]
