Hi
We are currently potty training our 2.5 year old. They will use the potty fantastically at home albeit it does not like us in the room and refuses (screams, shouts no) to use a public toilet or potty outside the house.

Has anyone got any tips to make them less scared/willing to use public/relatives toilets? I should add they aren’t keen on using our toilet despite a toddler seat and we are working on that but I need for them to be able to use a public toilet or every trip out will be 1 hour max and probably result in an accident. We are nappy free during the day and do not want to introduce one for outside times.

Thanks
