When my son was born, i created an email address for him. Every achievement and photo taken is sent to that email. When he is old enough, he will get the password and will have all those memories. Sharing this idea for those who may like it to do as well.
Hi Sage 
You can use Tinybeans to record ALL of your son's memories and milestones in one private space! When he's older, you can show the calendar view of his life (and he can see what grandma or his aunt had to say about this stage in his life too)
