SDs are 13 and 12. They live with their mum the majority of the time, only with us EOWE now through their preference, and DH pays maintenance accordingly. DH and their mum aren’t on great terms.
In the past, clothes have ‘belonged to the house’ so clothes get washed and returned. Very frequently, ‘our’ clothes go AWOL and return stained, ripped or months later, too small. I would say we buy nicer clothes for SDs but they’re perfectly adequately dressed by their mum too.
Having found last weekend that - yet again - they have “no clothes” here, I would like to suggest to them and DH that the clothes can travel freely with SDs, and we’ll take them on a couple of big shopping trips a year, and buy things like coats (we do this anyway) but they need to be responsible and bring a bag of clothes with them each time. I’d suggest we maintain a supply of pants and pyjamas and the very basics.
