I’m fairly confident the only reason I have a memory is thanks to photos (yikes!). If there isn’t a photo, there’s a good chance I won’t remember it even happened. Enter my excuse for having 18,564 photos on my phone at the moment. The baby years are going by way too fast, and I’m overly paranoid about missing even the tiniest moment. Monthly milestone pictures helped me capture their rapid growth during that magical first year — and I’ve never regretted the effort.

For our son, I used a set of fun letter board quotes to match each month. Here I’m sharing 12 sweet and seasonal letter board ideas for baby boys (though honestly, you can swap them around however you like!). These little signs made our milestone photos extra special and gave me an excuse to laugh at the silly meltdown moments that became some of my favorite snapshots.

My Favorite Keepsake 📚
At the end of the 12 months, I created a Chatbook with my favorite milestone photos. It’s priceless to look back and see the side-by-side comparisons of just how much my little one grew in that first year.
If you’re starting your own milestone photo tradition, remember: don’t stress perfection! Some of my favorite pictures are the meltdown moments over tiny, laughable daily happenings.
