Old Mommin’ — for the legends who became moms around 35+

Often labeled “advanced maternal age” (yep, the geriatric thing) at 35+, but we call it what it is: experience, intention, and strength. Own it.

If you welcomed a kid at 35 or later, you’re Old Mommin’—whether people raise an eyebrow at pickup or you’re rocking late-in-life mom vibes on purpose. It’s cool to be an Old Mom.

Old Mom = ~35+ when you became a mom
Seasoned & steady: patience, perspective, presence
Intentional time: you show up on purpose
Resourceful & ready: wisdom, humor, world-class mom hacks
Unbothered confidence: trends fade—love doesn’t

Throw on the Old Mommin’ gear and rep the ~35+ club with pride.

What is the origin of Old Daddin’?

Back in 2017, at an ultrasound, Robb (age 40) joked, “What does that make me?” after hearing his wife’s pregnancy called “geriatric.” The tech replied, “You’re an Old Dad.” The name stuck. In 2024, after a tough stretch, Robb turned that joke into a brand with just a few hundred bucks and a vision. With patches sewn by the neighbor, embroidery by his brother-in-law, and a family-run garage operation, Old Daddin’ was born. Today, it’s more than apparel—it’s a community for dads who wear their status proudly.
