Designed for Mom's by Mom's
Motherhood isn’t just a title—it’s a mark of love, strength, and resilience. It’s the sleepless nights, the to-do lists that never end and the moments of pure joy. It’s giving your all and somehow finding more to give.
At Hammer & Rattle, we celebrate the moms who show up every day—messy buns, coffee in hand, doing the impossible with love. Our apparel is designed to honor the incredible work you do while keeping you stylish and comfortable, because let’s be real—mom life doesn’t come with breaks.
So wear your mom badge proudly.
You’ve earned it!
"Being a mom isn’t about having all the answers—it’s about showing up, loving fiercely, and giving your best, even on the hard days. Your little one won’t remember the mess or the mistakes, but they’ll always remember the way you made them feel: safe, loved, and unstoppable."
