If you're at home, just go naked, it will save you going through pants and it might make it easier for him - the pants probably feel like a nappy, but also he might struggle to get them down in time
Our little girl has been potty training for what feels like about 2 months now we’ve just done it gradually! She started exactly the same, little wees CONSTANTLY never going on the potty even when I kept suggesting it etc but she is getting better! I do find she still thinks she has a ‘nappy’ on when she has pants on, so most of the time she is naked. Found taking her out as well means she has to hold it a bit longer
Naked on the bottom for a couple of days at home as he likely won’t like weeing on the floor and might be enough to spur him onto the potty/toilet. Our daughter never liked the potty so we went straight to toilet - could be worth a try!
Yeah my daughter didn’t seem to know how to go for ages then once day it clicked and everything has been grand since
