While children’s birthdays are exciting and fun-filled milestones, for parents they can be slightly bittersweet, marking the passage of time. All too soon, that little one will be packing his or her bags for college.

One mom takes the day before a child’s birthday to indulge in a little wistfulness.

“Today is my day,” writes Denise Stirk in Parenting.com. “Today is my day for reflection on just how far we’ve come and how much has changed since that very first day this tiny little baby joined us in this great big world. And I can’t help but feel just a little emotional — and even a tiny bit sad. Somewhere in between all the tears and fears, smiles and milestones, failures and accomplishments, and giggles and snuggles, another year has passed us by. Just like that.”
