Travel potty - necessary or not ? Which one to get?

FirstTimeMom💁🏻🤰🏻🤱🏻

Have an on the floor one and an over the toliet one - do I need one for travel ? What about flushable wipes - won’t it clog the plumbing ?

Do u use a piddle paddle thing too ?

My son peed in his car seat today and demanded we stop so he could poop in the toilet so I gotta get more potty training supplies before we formally train in November 😐 I wa slooking into the Oxo travel potty
