Gift Reminders

Some of you may know that the gift reminders are my little project and I'd like some feedback on what I can do to improve them. Also, we have a hard time getting people to put the year of birth on their reminder sign up. So many go out everyday for 0-3 birthday age and I know that can't be right. In order for me to design those for the appropriate age, we need the appropriate birth years to be put in. Any suggestions very much appreciated. I think this is such a helpful and fun project.
