How can i discipline my 2 year old?

[LMcmahon]

Any advice on how to discipline a 2 year old? My son has just turned 2 and all of a sudden he is so naughty!
He just doesnt listen to me. He plays with doors, taking great joy in opening and shutting them while i cringe for his fingers, he climbs on the chair so he can reach the light switch and turn it on and off, he climbs on the table...
It doesnt matter how many times i tell him no, or get him down, he will just scream and do it again. And again. And again.

How can i get him to actually stop doing it? Hes too young to understand the naughty step, which really works for my eldest, he doesnt bat an eyelid if i shout at him, or just use a firm voice. I just dont know what to do, at the moment he is totally getting away with this behaviour.
Any ideas?

Put him in your bedroom, a room without toys and books , and close the door behind you.

If he doesn't behave in a room, he is not allowed back in the room . Too bad if that is the room that has the tv in.

I recommend reading How to talk so little kids will listen.
He loves climbing so could you redirect his behaviour?
I'd try to avoid shouting too frequently as it'll lose its novelty. If you can, state the boundary, firmly but calmly, then offer choice -You can't climb on the table but let's go outside,

You can't climb on the table but let's go outside, would you like to climb on the slide or the climbing frame?

Toddler's are all about wanting power and it is natural for them to test boundaries. So by giving them a choice, you are letting them think they have some control/power.

Ask once, if they dont listen then physically move them, then redirect or distract. Then keep repeating. They get it eventually.

Repetition and consistency. It's a ballache but will help in the long-run. It helps to know that the reason they keep testing boundaries you've already enforced is actually because they feel more secure and safe when they know the status quo. They know it's a rule but keep testing to check that's still the case. But, y'know, in a really annoying way because they're toddlers!
