My nearly 3 year old son has been weeing in the toilet for past 6 months, but every time he needs a poo he insists on having a nappy on, he will then go and hide somewhere (has always done this), then comes back for me to take nappy off. He gets really distressed if i tell him there's no nappies left etc (he will go and get his baby bruv's nappy to wear). Don't know how to get him out of this, any ideas???
Also, he has no interest of using a potty.
