An exhausted mom left the house with nothing but a diaper on her bottom-half days after giving birth - going on a walk and to the grocery store before she realized.

Jahlen Johnson, 27, had just had her third child, Ryland, three weeks, when she decided to brave a walk and grocery run on November 9.

Her doorbell camera captured the moment she left the house - and loaded her kids into the car - with no pants on.

But it wasn't until three hours later that Jahlen realized she'd left her home in Atlanta, Georgia, US, wearing just a diaper and t-shirt - having forgotten to put on any pants.

Jahlen - who is also mom to Madison, 3, and William, 6 - blamed the mishap on the sheer exhaustion of postpartum life.

She says she is "irritated" with her husband, Jack, 30, a customer service rep, who helped her put the kids in the car without realizing she didn't have pants on. "

Jahlen said she noticed people were staring at her more, but wasn't sure if it was because she had a newborn.

Jahlen said: "I had just had a baby a week prior, making me a mom-of-three."

"During those seven days, I was stuck at home and just felt isolated. "

"I had been wearing a diaper and a t-shirt since delivering my baby because it was the most comfortable thing to have on."

What happened next was a mix of exhaustion and muscle memory, as Jahlen recounted: "When I randomly decided to take my kids on a walk, it never occurred to me I needed to wear pants."

"In my mind, I already had pants on."

After the walk, the stay-at-home mom and content creator was still feeling energetic and decided to head to the grocery store with her two youngest children in tow.

"We did the whole grocery trip and got home with me never once thinking about it," she said."

It wasn't until she got home and was ready for a shower that the realization struck.

"When we got home, I was exhausted and needed a shower," she said. "

"I gave my husband the kids and started taking my clothes off to get in the shower."

"That's when I realized I was wearing a diaper with no pants. "

"I was shocked and ran to my husband to tell him what happened, and he didn't believe me. "

"So I pulled up the camera footage to prove it, and we were both shocked we had missed it. He never even noticed!"

Jahlen's video - which she shared on social media - quickly went viral, resonating with moms everywhere.

"The reaction to it has been incredible," she said. "

"I haven't received one mean comment. "

"So many moms relate to the exhaustion that could lead you to forgetting your pants and leaving with a diaper. It's very relatable."

The overwhelming response highlighted just how common the struggles of early motherhood can be, with fellow moms sharing their own similar experiences of exhaustion-fuelled mishaps.

For Jahlen, the key takeaway - beyond the laughs - is a reminder that these moments are temporary.

"My advice to new moms is this will pass," she said. "

"The initial exhaustion doesn't last forever, and eventually you'll have a routine down."

"Also, more importantly, always check to make sure you're wearing pants."
