We have a carry potty for car journeys and places there aren’t toilets but anywhere there is a toilet we have a folding seat reducer like the one suggested above. Ours is green with froggy eyes and my daughter loves it, she calls it her frog-ogg and she likes to unfold it and put it on the toilet seat herself.
@Kerry ohh where did you get the frog one from? My little boy would love that! X
@Stacey not sure this is exactly the same one but ours looks very similar to this https://amzn.eu/d/cpSlUfh
We're not taking travel potty. My LG is potty trained since around Dec. When were travelling or out a d about we use this one (https://amzn.eu/d/cvu0XIK). She really likes it as she can go on a " big potty". When we're out and about for the day she does wear a pull up to avoid accidents but she's now quite good in telling us when she needs to go.
