My boy not 3 yet is fully potty trained, the problem is he's sitting on the potty even during pee time. Should I try teaching him peeing while standing or it will come naturally and just let him continue?
will come naturally and just let him continue?
You bet. If he doesn't discover it for himself, he'll sooner or later imitate other boys and men.
If it never comes naturally, trust me that you'll be very happy about it because you'll have much less cleaning up to do in the bathroom. Our boys all do it standing up and their aim leaves much to wish for, especially at night.
If I were you, I'd congratulate myself about having done a great job potty-training him.
I've heard of grown men who prefer to sit. As a woman who sits every time, I see no reason to think it's a problem. You are never in a bathroom that has no toilets. There is always a toilet, so it's always an option. My older son hates urinals because of shyness. He doesn't sit as far as I know, but I do know he will wait as long as it takes to use a stall simply to avoid urinals.
I would bet though, he will stand when he is taller. Many young boys aren't even tall enough to stand at a toilet. A stool is an option, but due to lack of coordination, balancing on a stool with pants at least partially down may not feel like the safest thing to a small one, particularly standing in front of a large hard object with a pool of water inside. My boys would stand because I used a small plastic stand alone urinal that was their size. I didn't want them to stand, I just bought it as an option because I wanted any item that would encourage them to use a toilet. I am of the mindset that if they are using a toilet instead of a diaper or your floor, rejoice & don't worry about the rest. The rest will sort itself in time. My one son was so attached to his urinal I bought one to ship to a relative's home because we were planning to visit & he would get very upset to use anything else to pee in at that age & I just wanted a pleasant trip without toilet drama. Her kids liked it so much I just left it as a thank you for hosting us.
