8 year old pees his pants...

Not sure what to do my 8 year old pees his pants in public when he is having to much fun and we have always asked him to pause for 2 seconds and use the bathroom but like yesterday he was an at chuck r cheese for his 8th birthday and he was playing a bunch of games and peed his pants and also a treehouse running around on the jungle gym he also peed his pants I’m tempted to just start buying him pull ups for when we are out doing fun things cause he will not stop playing to use the bathroom.
