I’ve realised, quite some time ago, but still don’t remember, that asking a three year old the question “are you sure?” is pointless because they do not understand it. For example:
Mummy: “do you want to go to the toilet?“
Lilly: “no“
Mummy: “are you sure?“
Lilly: “no” – therefore if she understood that she’s contemplating and she’s now wondering if perhaps she does need to go. HA!
But I still say it! Every time! Can’t seem to help it! Must be the epilepsy 😉 (Gotta use that word in some context don’t I?)
