Daughter stealing younger sisters clothes

[VALCITY1990]

Hi all

I have 2 dds DD1 15 and DD2 12

Dd1 has a Saturday job helping out her friends mum at her hairdressers with the money she earns she treats her self to expensive clothes make up trainers etc however DD2 Has become very jealous as I can't afford the things she buys due to money being tight and being a single mother.

DD2 out of jealousy has started to resorting taking her stuff and then denying it even tho they have been found in her room in talking everything you name it,
shirts skirts trainers make-up even her own UNDERWEAR!!! I do the washing so I know there not hers! Every time DD1 confronts her if always ends in a screaming match!!!

It's just non stop arguing and I am up my wits end with it

Any suggestions please will be great to

I can't put a lock on the door as they share a room!

Is it possible to move or clear out a room so that the both of them could have their own room?? They both need personal space and a room to call their own.

As punishment, take her phone, no friends for much longer...and get your younger one a job some place. .or have her volunteer somewhere...for a while..

This isn't to be taken lightly. Stealing and invading someone else's personal belongings is wrong. She isn't entitled to her sisters belongings.

Also, if they both share a room, how do you know that she's taking things?? How do you know that it isn't your oldest trying to get her in trouble and perhaps get a room of her own by creating these problems??
