He will be 4 in December!
It has been an uphill battle, even Cod was stumped.
I let him choose pants, potty and toilet trainer seat and he point blank refused to take his nappy off.
I finally had enough last week after a really dirty nappy, dh came home, showed him what to do for the millionth time (again!), and sat for ages with him in the bathroom reading him stories etc. Eventually he did a wee and was so proud of himself. Dh, dd and I were all whooping round the house like loons. We also coaxed him by telling him he wouldn't be allowed in the school nursery unless he went to the toilet (he is desperate to go "school" like his sister). He now hates nappies and wont even wear one over night and has been dry in the night ever since.
Maybe he was just ready now, I dunno.
I was so sure he would be the child to go to school in nappies.
Good luck with your ds, I wouldn't pressurise him, if my ds can do it eventually any child can. Keep me posted.
