So 5 yo spilt something, didn't tell us, didn't tell him off just told him to tell us in future and helped him change his top. Hr later puts feet on me and his socks are soaked, turns out from earleir. Clearly not scared if have told him off so must just not bother him.
He's the same if he had an accident overnight and leaks, no issue lying in it, doesn't come and tell us and isn't overly distressed (he's in pull ups overnight so it's wet not flooded)
Plays in the sink he'll put the cold tap on full and play in that until his hands are freezing.
Is it just being 4/5 that he doesn't notice / mind the sensation?
