Get one of those portable potty’s that you can carry around. Keep asking them if they need to go. Keep reminding them to tell you etc x
We started potty training our 2.5 year old on Saturday and went straight out that morning to do a food shop and spent nearly 3 hours at the park that afternoon. He stayed dry for over 3 hours in the morning and told me twice when he needed a wee at the park (albeit had 1 accident) we’ve been out every day since and he’s not had a single accident. We bring a travel potty and he tells me when he needs to go. Although he can stay dry for hours so I wouldn’t worry, they should be able to hold it for much longer than 20 minutes! Also I didn’t bother putting a nappy on him in the car, just made sure we took him to the toilet first and then popped a puppy pad under his bum in the car seat. Personally I’ve found the less stress you put on it, the better it goes! Just bring lots of spare pants and trousers xx
I would get a travel potty to take with you… maybe limit his drinks an hour before you leave? Make sure he does a big wee before you leave… and if you feel you want to use a pull ups I would do it over his pants so when he wees he feels wet…or get some puppy pads to save your car seat (that’s what I did)! X
We do pull ups for travel, even if it’s just to the store. He usually wets it while in the car, but once we are to our destination he will let us know he needs to go. I think being in the car gets him out of the mindset of holding it since he usually falls asleep
I would try to take him every hour or so while you’re out. If you can, get him to go just before each car trip. I did what you did and spent 3 days at home then started to do trips out of the house. We never put him back in nappies after that first 3 days and he never had an accident in the car (just occasional one out and about if he got absorbed in an activity and forgot).
How old is your child? Going to the potty every 20 minutes is crazy and unsustainable, if they can’t go longer than that then they just aren’t ready. Definitely stick to underwear, putting a pull up now would just cause confusion. Spread out the time between potty visits and see how it goes, really they should be telling you when they need to go, with a bit of a nudge from you if they are distracted or if a long time has passed.
