DS1 (4 in Sept) has started denying all knowledge of how DS2 hurt himself, why he is crying, when it is almost certainly down to something he has done. Insists he has washed his hands after going to the toilet, when I know he hasn't. Nothing earth shattering, and I don't tell him off, but I would like advice on how best to explain why we have to tell the truth in a way he can understand. Any tips?
Thanks,
Bloss
