First diaper blowout story

Took my daughter to the grocery store yesterday, just the two of us for the first time. Got through the whole trip fine and was feeling pretty confident. Went to change her in the car before driving home and it was EVERYWHERE. Poop up to her neck, all over her clothes, the diaper bag, my shirt. I just stood there like an idiot trying to figure out what to do. My wife is laughing at me now but I'm buying a hazmat suit for the next trip lol.
