Potty training while out

Rana

This may be a silly question, but what do you do when you’re in a public place with a two year old that has to go? At home we have the toilet seats that fit him, and he can go by himself, any where else do I just have to hold him on the toilet? Or do people get the fitted seats and carry them around in a diaper bag? 🤷‍♀️ Am I massively over thinking this? (Yes, the answer to this is always yes)
