I feel silly asking but I need some pro tips!

My 3yo is pretty good about using the potty now (just recently started forcing the issue, he would be stay in diapers forever). But man it can be a mess. He usually gets there, but even pushing his penis down his aim seems awful, especially if there is a lot to go - water pressure straightens it out maybe? He ends up going a little in the bowl and a lot on his pants, shoes, floor, whatever. At home we can remove pants but need to figure it out for school etc (he just goes 2 days a week). Also the laundry, yikes.

Is standing up going to help or be just as bad in a different way? And how do they go standing up in a public bathroom or anywhere with a full size toilet and no step stool?

Training a girl was so much easier I keep telling my husband he has the equipment, he needs to teach him but that’s not working! Ha.
