Well, my sister-in-law found this awesome calendar by Carter's. It's so great and makes keeping track of milestones super easy and convenient! I hung it up in the nursery so I can easily just jot down milestones on the calendar as they happen. At the end of the year, all I have to do is look back at the calendar for exact dates to add to my baby book. The calendar comes with stickers that also make it easy to add on dates.
Such a great product! What are some ways that you've managed to keep track of milestones with your children?
