If you’re looking to do something special for your child’s 18th birthday, make a sentimental email address for them! When they are born, create an email address to which you will send them photos and notes about special days and milestones they reached as they grow up. You can even have their friends, siblings, grandparents, aunts, and uncles send them emails–so long as they keep it a secret! Then, on their 18th birthday, give them the password to their email. You could even host a party for the great email reveal. Your child will certainly love looking back on old memories and accomplishments as they officially enter adulthood.
