DS is now 3.2 and also not ready 
Also feel we have tried almost everything. He is very stubborn and just does not want to do it. Also still in pullups when we go out anywhere otherwise we are guaranteed puddles. He just wees in his pants, it doesn't bother him at all. I will ask and ask if he needs to do a wee or a poo, he says No, no, no then sometime later I will notice the wet patch or the smell. he keeps playing quite happily, really not bothered by it.
The only success we have had is when he has no pants on at home. Then he mostly wees in the potty. Although recently he has taken to weeing on the sofa or rug and thinking it is hilarious.
He dances around when he needs to do a poo and will eventually do it on the floor, completely ignoring my entreaties to use the potty. If in pants or a pull up he will do it in that.
I have actually almost given up and have started potty training his 16 mth old brother. DS1 is not motivated by seeing his younger brother on the potty, he just says yes, put DS2 on the potty!
No advice, sorry, and also feel quite despairing. All his little friends are potty trained, he is also not in the slightest motivated by seeing them using the potty or toilet. He just doesn't want to do it.
I also feel like the only mother with a 3 year old still in nappies. With no answers or end in sight. Health and childcare professionals all tell me not to worry, boys take longer to train than girls, he will get it eventually...
But when???
