Dd16 has recently decided she’s got an aversion to dd12 not wearing socks. Dd prefers to have bare feet after she gets home for the day and this has been going on on and off for a while now but the last week or so it’s been every night, screaming and shouting, crying, telling her little sister she’s disgusting. Im pretty sure she’s heard a friend saying they hate feet as usually these little quirks are copied from someone else and are forgetten about after a few months. It’s just started again and I’ve had to leave the house as am at the end of my tether with it I’m a single parent working 3 jobs to pay for their hobby, am exhausted and want to chill on the rare evenings I am at home. Last night it was just as we sat down to the tea dd16 had requested and I’d spent ages making and I ended up going to my room instead of eating. I’m going to have to go back as dd12 is messaging me begging and saying she’s throwing things at her and screaming but I just can’t cope with the meltdowns anymore and needed away from it as no amount of reasoning was working. I used to just tell dd to put her socks on but don’t feel she should get to dictate something like this so have stopped and this is why it’s escalated. Any advice. I’ve had no problem with her in 16 years apart from some bits of other nasty words towards her sister from time to time so minister of this is just an excuse. I highly doubt she’s truly triggered by her feet. No other issues. I’m stumped!
