When my kids were little we only had to keep track of the 7 birthdays of our immediate family. As they kids all married and had children, 7 turned into 30. What a delightful problem to have, right?
I have a pretty good memory. I've added these dates to many calendars over the years, but I started to forget how old each grandchild was and what year they were born.
Yikes! I might miss a milestone birthday. I like being prepared ahead of time for the milestones. We celebrate every birthday, but we have traditions at certain birthdays, like blessings, baptisms, ordinations, acceptance to Hogwart's, etc.
On the Birthday Milestones page I write the name and birthdate complete with the year, then add their age in every year column. Then I highlight the milestones. That way I know how many milestones to prepare for in that year.
On the Gift List page I include the ages to remind me to find age-appropriate gifts as well as the milestone gifts. On this page I list all of the birthdays in order of the month they fall in, kind of like a perpetual calendar.
I list the birthdays in order and leave a couple of blanks in each month for additions to our family. I think we are done having new grandbabies but I have room for surprises.
You can also use the gift list page for Christmas. It's never too soon to plan.
