Diaper blowout at the worst possible time
Taking my daughter to meet my parents for the first time. We're at their house maybe 10 minutes and she has a blowout that goes up her back, down her legs, everywhere. Got poop on my shirt, the car seat, her outfit. My mom tried to help but seemed kind of judgy about how I handled it. Anyway we're fine but wow nobody tells you about these explosions. Brought extra everything now.
Oh man, been there. Pro tip for next time: bring like three extra outfits in the diaper bag, not just one. Your parents will understand, trust me.
