Suitable punishment for

[LiteraryDevil]

11 year old who left my hair straighteners plugged in (but not switched on) on the landing carpet. The straighteners are mine, she is not allowed to use them by herself, and was told 2 days ago that she isn't allowed because of the risk of burns and fire. Her 3 year old brother is likely to have flicked the socket switch and I'd have been none the wiser until they burnt her brother or the carpet as they were on the top floor and I wouldn't be going up there for the next hour.
She has already lost her pocket money this week and is banned from all screens for this week due to consistent disobedience and ignoring punishments already given. She doesn't play out by herself as not safe to do so here so can't ground her. Any ideas?

I wouldn't punish this. I would talk again about how she isn't to use the straighteners because of x,y and z and that if you have to speak to her again about it then you will issue a consequence.

Maybe not using the straighteners at all, even supervised, for a while. (She seems to have a lot of black marks against her this week - she may as well be hung for a sheep as a lamb! Not much else you can do for punishment, other than keel-hauling her or a lengthy prison sentence..)

She's particularly troublesome this week. I'm on ear and out the other with a good dose of attitude and cheek.

I only straighten her hair for special occasions as isn't curly.

Both daughters are off to their dad's this weekend so we will have a fresh start on Sunday night/Monday morning. Tonight I am going to get them to sit down with me and write a list of house rules and consequences for breaking those rules. We've done this verbally before but they want it doing properly and laminating I will also do their chores and rewards "properly" to remind them. They have actually asked for chores to earn pocket money so quite pleased as as a single parent to 3 then I appreciate them chipping in to help with things like setting the table, clearing the dishes away etc. Hopefully this will work! Otherwise it's Borstal!

While I can understand that this is probably the last straw for you, it does seem a little over the top to punish your DD for this. I have personally found that punishments just escalate once they are over 10, it doesn't really work. From you description you have the same problem - punishments are ignored and gives more unwanted behaviour.

She is old enough for you to have a chat to her about safety. I think it's a very good idea that you have a chat about house rules. I think there is a good chance that both your DD will live up to the responsibility. Just make sure you notice when they do their chores and praise them.

Don't link everyday chores to pocket money. You are a family community-you all chip in to get stuff done. But have a list of extra jobs that they can earn extra money for. Be careful about too many house rules and too many punishments-they are counter productive in the long run. Just have a few common sense "making life easy" things and make sure that they apply to you as well.
As for the straighteners-one of the rules has to be not going into each other's rooms or touching each orher's stuff without permission. Is she old enough for her own straighteners?
It sounds as if there have been a lot of sanctions. Could you say that the new regime starts on Monday and wipe the slate clean?

Don't punish be nice. Take her aside and calmly talk about what happened, what could have happened with the three year old, look together pictures of burns and their consequences and house fires and loosing everything.
Be nice. At the end (when she gets it and feels awful), give her a cuddle and a treat, because it could have ended badly but didn't and you both know that she understands how important it is to be careful and why their are rules about straighteners.
