Growing up my sister Hillary was the baby of the family*. She was always well heeled, coordinated, organized and cute. Her baby, Nora Jane (age 8 days) will doubtlessly be the same way. Love this picture of Nora Jane taken by Kristine McNairy. I think the idea of a birth announcement with the baby on a vintage scale** is genius. You could also do cute ones with measuring tapes or rulers.
*Hillary was brutally replaced as baby of the family at the age of 10. This lead to many painful conversations with our parents, about why they would "do IT again after 10 years", not name the baby "Linguine Alfredo", and why telling everyone it was my baby was not a good strategy.
**Yes, that scale is accurate. At birth NJ was a very healthy 8lbs 9 ozs.
