I did this for DD1 and when we settled on a name for DD2 I did the same thing. Thought I would share with all you ladies.
Once we decided on our babies name I signed them up for a google email account (using their first and last name, example MarySmith@gmail.com) then I started emailing notes or photos to that email address about once a month or so. I figure when my daughters turn 18 I will hand over the email and password and they will have a few years worth of amazing emails from me from before they were even born! I have not shared the email address with anyone because I want the emails just from me and I check every few months and clear out any junk mail.
Just thought I would share this idea with all of you. It is kind of like a high tech diary!!
