7 Reasons Why 500,000+ Moms of Toddlers Are Replacing Their Diaper Bag With This Hands-Free Bum Bag That Holds More Than It Looks

I had seen the ads and assumed the usual. A flat bum bag does not hold a toddler's errand kit. So I packed it on the kitchen counter to prove myself right: my phone, my wallet, my keys, one diaper, a travel pack of wipes, a fruit pouch, my sunglasses, the hand sanitizer.

It all went in, zipped, and the bag still sat flat. That is the whole trick: the main compartment is deeper than the shape lets on, so it holds a grocery run or a park afternoon without looking like it does.

I needed our usual errand kit to fit. That was the test, and it passed.

The diaper bag made sense when she was tiny and the bag was mostly bottles. By the time she turned two, a quick errand meant one diaper, wipes, a snack, and a change of mind every four minutes.

I was still carrying the whole bag out of habit, plus my purse, plus her. For those short trips, the bum bag replaced both: her basics in the main compartment, my things in the pockets, everything on one strap.

The diaper bag stays in the closet for the long days. It no longer comes along for every errand.

The car seat is where every shoulder bag I have owned fell off. You bend in to buckle, the strap slides, the bag swings into the child, and you stand up with one hand holding the bag and the other holding a buckle you have not closed.

This one is worn across the body and sits flat against me, so it does not swing and it does not slide. I bend in, buckle with both hands, and stand up with the bag exactly where it was.

Both hands. At the car seat, at the cart, on the sidewalk. I had forgotten what that was like.

The tote dug a groove into my shoulder. The crossbody I tried had a thin strap that cut in by noon. The diaper bag was fine until it had anything in it. Every one of them got demoted for the same reason.

This strap is wide and sits across my body, so the weight spreads instead of hanging off one shoulder. It adjusts up to 57 inches, with room for a petite frame and a plus-size one, and it does not ride up.

I keep it on from school drop-off through the afternoon errands. I stopped shifting a bag from one shoulder to the other.

Count how many times you bend over in a day with a toddler: the stroller, the shoes, the dropped cracker, the dropped cracker again. Every one of those was a chance for my old bag to empty its front pocket onto the sidewalk.

Here both zippers are on top and the bag sits flat against me, so when I bend to fasten her shoes, the pockets stay zipped and stay against my body. Nothing has fallen out, and I have stopped checking.

Phone in the back zip pocket, keys in the front zip pocket, the small things in the internal pocket inside. Everything has a place, and the places stay shut.

The cart was my purse's second home. Toddler in the seat, purse in the basket, and by the time we reached the register it had disappeared under the groceries. I moved half the shopping just to find my wallet.

Now the bag is on me. Both hands for the cart and the child, wallet against my hip, and at checkout I unzip the front pocket without moving a single bag of groceries.

It sounds small. Ask any mom who has pushed a cart one-handed because the other hand was holding a bag.

Right now it is Buy One, Get One Free: pick Buy 1, Get 1 Free on the product page and choose two colors or prints. I kept both of mine: a black one that goes with everything, and the print my five-year-old picked. Same pockets, same strap, different look, and more than fifty colors, patterns, and materials to choose from.

Then I did the thing I had been avoiding. The other purses went to the donation bin. The diaper bag only comes out for the long days now, and the bum bag does the rest.

Two bum bags, one errand kit that moves between them, and I reach for one of them every morning.

Like every mom I know, I checked the reviews before the cart. Twice. Over 500,000 women have ordered from Emmafy, the bum bag alone has 10,000+ five-star reviews, and this is the one that put it in my cart:
