My little one knows that there are stash & dash bins in the garage. She asked last night if she could "get some Barbies". It took me a moment to understand that she meant dig them out of the various stash & dash bins in the garage. I told her she could, but she'd need to find as many toys to give away as she wanted garage items. She immediately went and grabbed ten things. Wow!
So, I had to keep my word.
I just finished two hours of stash & dash sorting. I filled three bags of recycling and three of donations. I donated things I don't like in the house, as well as items the kids have definately outgrown. I consolidated the bins, eliminating two of them through the donations, trash and recycling. It's still not done, but it's much better and tidy enough that the little one can pick a few things to bring back into the house.
Having a garage is good for me, because it allows me to let things age. I was able to give away items I'd kept in an earlier round of decluttering, because there is enough emotional distance now. It's what works for me. And each time, it gets easier.
