what do you do? Dirty butt...NO changing table!

Brittany
You're in a public place, with baby in the car seat/ baby wearer and your diaper bag. There's no changing table and you can't use the seat that lays down in the stroller because you left it in the car....
Aside from the instant rage and wanting to just flip your baby's butt out on a restaurant table or counter in the store (I would never do....but would definitely love to 🤣) 
How do you manage??
