* I use a year instead of six months because occasionally you get that holiday-specific stuff that might be good to keep but only comes up annually.
When single I changed countries every 1-2 years (moved a lot around Europe). I learned to live with very little, but it isn't as easy when you have wife/kids (and uprooting your kid just for the sake of minimalism isn't really fair).
Wife and I talked about moving in a couple of years, but I'm reluctant because of the kid.
- Offer a tablet to your wife
- Buy reusable diapers (it's more trouble, but cheaper on long run)
- Explain to the wife about the dangers of some plastics (BPAs, phtalates) and convince her to buy form local artisans (without trying to be political, tell her some of the toys are made by kids not much younger than your own)
- Put stuff in boxes you know she won't use. Store them away from her (a shed, storage unit, etc). After a year or so, ask her if she knows where item A,B,C is, and if she needs it. More likely she will have no idea where it is. Explain to her that if the last year she didn't needed that purple striped sweater, she probably won't need it ever. Suggest selling or donating.
- Ask for hand-me-downs from friends and family for your kid. It will be harder for he to justify buying new clothes ('But he needs a new pair of trousers') when you can point to the bunch that was given to you.
I think just those 5 things reduced a lot of the stuff we have in the house.
You will have to manage this of course, you can't expect everything to go your way. She will buy that dress/shoes, but avoid you doing it too just because she tells you also need new shoes. Also, we go on vacation (for her benefit as I really not into it) every once in a while. It is a partnership after.
Wanting things is a legitimate choice, and it seems unfair to deprive someone of that choice through trickery.
All the other things I talk to her, explain. Why buy new clothes every 2 months (seriously, the damn baby just keeps growing) if we can have a lot of hand-me-downs? She loves her kindle and iPad. The toys issue is a real concern and made it her concern as well. I started drinking a lot less because it was a concern for her.
I don't think it is manipulation. I hate clutter, she knows it, I try to find solutions where both are ok with it. I mentioned sometimes I get my way, sometimes she gets her way. I can't say for others, but I never found anyone that was 100 percent match in everything I like and believe. I mention it is a partnership. I hate going on holidays, hate it, but I go to make her happy. Of course I expect she does a few things to make me happy. If not (both sides), why the hell are we together? Just to save on rent?
Edit: Heck, if you read the top post, you even see I'm going back to work because I want her to have things she really wants.
Strongly consider moving to ebooks for almost everything
Empty out closets (after eating a meal). Force yourself to throw out most of it.
Stop waiting to file. Throw it all in a drawer, go through said drawer infrequently at scheduled times.
