DS thinks going in naughty corner is funny

[Birdly]

DS is 2.4 and, although a lovely person really, can be very destructive. We've locked away as many of our things as possible but it's impossible to have everything out of his reach.
Today, he emptied the contents of one kitchen drawer into a sink full of water. Later, he threw his lunch piece-by-piece up against the fireplace while I was in the kitchen getting something for DD.
I know this sort of behaviour isn't especially unusual in boys of his age but I'm struggling to know how to deal with it and how to get him to understand that he shouldn't be doing it. I explain to him quite sternly that it's wrong, then put him in the naughty corner for a minute - but he finds the whole procedure funny, and starts to giggle. Not surprisingly, this winds me up even more at a time when I'm already pretty frustrated.
Any ideas, please?!

find a different punishment. you don't punish a child, they punish themselves by feeling punished. he doesn't give a crap about the naughty corner, so as a punishment it's about as effective as a chocolate teapot.

my case is a bit different cos my kids are autistic, but none of the 'standard' discipline methods worked. so we sat and thought. you know your child inside out and upside down. what does he HATE. with my ds1 it was the sound of the hoover. bingo. a punishment. we put the hoover on.

Hi
had the same thing with my son. As it happens he has special nedds so I had a handy ed psych to help me. His advice worked with ALL my kids. I would drop the stern talking too. He is too small to "get" lots of language , however bright he is, - so at the moment - from his perspective - he does something fun and then gets rewarded with lots and lots of attention from you. My ed psych illustrated this brilliantly by miming out what I was doing. If you took away the language the stern face and the finger wagging was hilarious - I would have done it as often as possible.
If he really acts up then just go to him with the MINIMUM of 'chat' and fuss and then remove him to somewhere really boring. I used to use one word for SN son ( "NO!" - said firmly not shouted) and for other kids just a short phrase to tell them that what they were doing was not ok.
You have accidentally turned the consequence for what he is doing into a fun game. Find somewhere other than the naughty corner and cut out the language and 'fuss'. It may help.
I kept trying the finger wagging thing for months before I changed it and his behaviour improved really quickly. The key is the consequence has to be age appropriate and something they don't like.
You can either talk to him afterwards about why what he did was naught or just let the actions speak until he is a bit older.
I hope this helps - speaking as one who found son urinating all over entire cd collection and ( literally) pissing himself laughing.

...."special nedds" !!*?...LOL!

I think I shall keep that . My son has special nedds - phnar phnar.
