Address Your Child
From the moment they're born to the time we depart this earth, our children will always be our babies. Even still, as you begin your love letter, address your child from the point of development they are currently in and open your love letter with a bit of record keeping for future reference. If you're writing to a newborn, take note of their growth or milestones. Make mention of a school aged child's grade level or an adult child's major life accomplishment. Your child's identity and journey is constantly changing, so taking stock of their growth with statements like, "this summer you turned four and officially became a swimmer!" will help with reflection of the letter when they're older.
