Caveat - she’s been staying with us for 3 weeks and we can have a rather strained relationship so I MBU and not her.
She has a weird thing with food where she refuses to share with anyone - fine. But she will literally sit in the living room and eat bags of sweets and chocolate bars in front of the children and will not give even one to them. They are kind of used to it now but tonight we’d all gone out for dinner, came home, kids are washed and ready for bed, teeth brushed and she sits down and opens a big share bag of sweets and proceeds to pop one in her mouth every ten seconds.
Youngest starts complaining - told clearly “no these are nannies”. Silence in the living room except for the crunching of bloody sweets every 10 seconds 😡
