I know if I were registering anywhere at all...I would ask for everyone to spend their money on our account at the local crunchy consignment store for mothers and children. It's so super poshy boutiquey and awesome and has EVERYTHING you could imagine needing from cloth diapers to gear and clothing for women and babies from newborn through teen years. There is a used side (that hardly even looks like second hand stuff, because they only accept things in pristine condition and won't take anything with disney characters or tacky things on them) and a new side that is ALL fair trade, organic, etc etc....it's AWESOME. One stop shopping that is so incredibly cheap, you can't even handle it...and it's all name brands and super good, high quality stuff.
Do you have anything like that in your area? If you don't know about it, can you research and try and find something? It is worth finding out! Buying brand new stuff is SO expensive and they grow out of it in NO TIME. Like, within a week of being able to fit in it. I can't tell you how many times I've picked something up and been like "ohhhh, this is so cute, shame they didn't even get to wear it!".
My kids wear adorable clothing, high quality, lots of organic brands, european brands, expensive US name brands and REALLY adorable styles...and for what it costs to buy a few outfits NEW, I can outfit them for an entire season. Really, like, I can walk into this place and drop $100-120 and buy everything they need from shoes to hats, coats and everything in between for an entire 4-5 month period...and people think I shop super high end places to find their clothing.
It's worth looking for this type of place...it makes it much more fun and cost efficient to shop for your kids and also gives you a place to bring the clothes back to consign when they grow out of them. Its also a cool "community hub" for other "crunchy types" and we always have so much fun when we go. I meet girlfriends and we shop while taking turns watching the kids as they play with the other children in the fun little house in the middle of the store. They have AWESOME books, slings, glamour mom stuff, just EVERYTHING. I would highly recommend you find a place near you like this. Consignment shops like the one we go to are popping up everywhere these days because people are catching on to how awesome it is to shop for less, get good quality stuff and buy what's already out there instead of putting money in the pockets of slave labor supported companies to buy up brand new stuff. Not to mention being able to consign things once your kids grow out of them...which keeps a pretty nice flow of money coming back into your account at the consignment shop. It's a good way to go about it!
