Parts of toys and puzzles everywhere

[Constantbronchitislaryngitis]

Hi
My girls are 10 and 6
I really need to declutter toys and organise again
But I don’t know where and how to start
I’m tempted to just throw it all in a recycling bin
There are pieces of puzzles and parts of sets in wrong places
The only thing I’ve ever managed to keep organised is Lego
I started trying to collect the same pieces together and put them in piles
It was taking so long
My 6 year old mixes everything up despite me having boxes for everything with pictures on them
I’ve got a chronic illness and just don’t have the energy for this
What have you ladies done?
