It is sort of a strange assumption that b/c one might spend money on diapers that their income is/isn't at a certain level. We don't know what else the mama might be (or not be) spending money on.
I never have to buy clothes for my children b/c my circle of family and friends always passes down clothes. Heck, I'm sitting on 10-12yo sized clothes for a petite 8yo. A BIL gives me money to the Gap every Xmas to buy church/nicer clothes for the kids (its a very generous amount-- and I stretch it by buying off season, etc to get sales!!).
Anyway, I also shop for myself at Goodwill if I need anything. My maternity clothes are all just oversized clothes from GW. (Thankfully my job doesn't demand professional-styled clothes!)
Our cars are always paid in cash, maintained by dh and we drive them til they die their 200K mile deaths (well, if we're lucky enough to get them that far!).
We live on one-income and my children want for nothing. Are we rich? Thats a strange question. By most standards, no. Do we live better than many who make 4x my income (dh is SAHD)? Yeah, we probably do. Why? Because we don't spend much money.
That said, I have fallen in love with diapers. How long will it last? I don't know. I set a limit for myself and I've stuck to it. I'm exploring a variety of diapers/covers so that i can make my own.
My heroes are the women who are making their own amazing products and re-cycling and doing it with little money put into it. But I definitely enjoy hearing about all the amazing diaper stashes of those who enjoy buying. I don't begrudge anyone their stash. I'd be disappointed (even tho its none of my business) if they were spending the money on illegal drugs. But to make beautiful cloth diapers part of their child's wardrobe-- I think its pretty neat. And b/c of their experiences, I'm able to learn so much more.
So, if you're one of those spending the money... I thank you for sharing! And if you're one of the make-your-own...I thank you for sharing too!
