Making it to your first Mother’s Day is a big milestone.

And yet, you’re both happily here. Depending on when Baby was born, you might have already witnessed the mini miracles of that first smile, a real giggle, maybe even crawling and actual first steps. So many moments to savor and celebrate, which is why you need the cutest first Mother’s Day onesies to honor this momentous time in both your lives.

You’re bound to snap a lot of pics of your baby on Mother’s Day, especially if you’re a new parent, and you’ll want them to be as stylish as possible. And while themed outfits might not be your thing, you’re definitely going to want an ensemble that commemorates the occasion. Because even though you and your little one will get to share many Mother’s Days together in years to come, you only get one first one.
