how to get my son to poo in the potty?

Spanking will not help, it could make it worse. Stop putting diapers on him, if he poops his pants clean it up and make a simple statement like "Oh we poop in the toilet" Relying on diapers is only making this difficult for you and him, confusing mainly for him. Stop using diapers and yes you may have to clean up some poop but he will learn faster.

You are allowing it to be a power struggle and you shouldn't. Back off. When he is ready, he will start doing it. Praise him a lot when he does and say nothing when he doesn't. He probably likes having this power over you and you will lose a lot of battles with him the future if you let him have that power. The normal age for full potty training for a boy is 3 1/2. Don't push it. Why does he have to do it on YOUR timeline? Let him choose. When he poops in his diaper, take it off him, walk him to the potty. Tell him poop goes in the potty and have him throw it in there. Then you both clap and cheer. Make it a came, not a battle. Some kids get freaked out if you flush this "gift' while they are there, so flush it out of his sight, or let him flush it.

DO NOT SPANK HIM!!!! You never punish a child for going to the bathroom, no mater where he goes.. And spanking does nothing for changing behavior. All you are teaching him is that it's okay to hit if you are bigger or in power. And what, exactly, is the line between hitting your kid and beating your kid?

I had the same problem with two of my children however girls. They refused as well so finally my husband and I came up with letting them around naked. My youngest is 3 and finally completely potty trained but we were in the same shoe up to a few months ago. I thought give it a shot since it worked with my older daughter. This way, underwear would not get soiled and have to be washed and diapers/pull-ups would not give wrong message.Luckily, it was over the summer so she ran freely my youngest, however, only on hardwood floors. Believe me she did not pee on the floor. She knew to use her potty but this way she could not poop in her underwear. It took a few days but she finally poop and with lysol quickly cleaned it up the hard wood floor. She was a little upset she could not go to some parts of the house so as a reward she was allowed to run nakie through the house. After a few more times pooping on the floor she transtioned nicely to her potty.

i think he is too young for a spanking.

he would get confused and think he had been spanked for going poop.

go to the library or bookshop and find a couple of kids stories about how big boys poop in the potty.

get rid of the diapers. he cant hold it in forever. when my son first got potty trained, i still put diapers on him at night and he would wait till i out a diaper on him then poop so when i ran out of diapers, that was it. he started going in the toilet. if he goes at the same time everyday, then have him sit on the toilet till he goes

stop giving him diapers, completely
