At the time I had my first baby (31 years ago) I was working for a manufacturer's rep. We had a stamp made showing one line for item ordered, ordered by, order date, shipped date, weight of shipment, etc.
I went to the office supply place and bought a sales type pad. I stamped the stamp on the pad. I backed up by 9 months and put the ordered date and by whom (us), item ordered was baby's name, shipped by (the OB doctor) and weight and lenth, etc in that blanks. When the next two babies came I used the same stamp and pad. Everyone thought it was a novel way. You might create something along those lines for your baby.
Congratulations!
P.S. I co-own a diaper service (the type that picks up dirty diapers and brings you clean ones). If someone would like to purchase a time period of the service you can have them call ###-###-####. Details can be found on www.earthbabydiaperservice.com. We're new and am trying to spread the word out there to all new moms.
