DS holding ALL wees and poo until nappy on at bedtime

[YummyBelicious]

He's totally fine on wearing pants, really interested when his twin goes on potty (he has been clean day and night for a few months)
We can go out for the day etc etc and no accidents
As SOON as we put nappy on for bed time he goes within minutes.

I thinking of going cold turkey fully on nappies Inc bedtime to stop him relying on them
Or would you say he's just not ready (3.3yrs)

Thanks x

Has he ever weed or pooed on the loo or in a potty?

Not really.
A few drops a few days ago on separate occasions. But that's all x

He's not toilet trained at all then really, is he.

I'm a nursery teacher and my advice would be to put him back in nappies all day and start again with the toilet training in a couple of months when he is back to weeing and pooing at regular intervals throughout the day.

It is really not good that he is withholding all day - that must be around 12 hours?

No he's not
That's what I'm saying, it's his twin that is trained if I've not made that clear sorry

I have remembered that he's been on the toilet at preschool twice for his teacher, and As a personality side note he is incredibly stubbon so not sure if he's just playing me a bit?

Up until 3 days ago I was using pull ups too and he woukd wait until I used one to go in
So stopped using those so as not to confuse him

I don't think I explained myself very well at first sorry

I'm still a little bit confused - sorry!

So, has he been in nappies/pull ups all the time until 3 days ago?

If he's only been withholding since then, I would put him back into them as it doesn't sound like he's ready.
