I'm a bit of a hoarder to be mild. I'm working on that and making lots of good progress.
I'm going to start packing away some of my daughters summer clothes. She is my youngest so the only one with too many clothes still. I won't put everything away but I do need to put a lidded box worth under her bed to make room for some bulky winter bits in her wardrobe.
So when do you think out kids seasonal clothes. I did it as I unpacked for this summer and dd tried on the things that looked small and we donated it or Vinted it while people could still use out of it. I'm not 100% sure what will fit her next year, but I know what she didn't wear at all this year.
I'm not buying her clothes any more until she really needs them btw. There's no shopping for a winter wardrobe. She hasn't grown much in the last two years
