My mom sent me this article (click here) from Seventh Generation; it's a guide to recycling infant clothing and gear.
We all know babies grow fast and most baby stuff is outgrown long before it's obsolete or worn out.
This article lists resources for unloading your baby gear, and for finding used/recycled clothes and gear.
"Buy only what you need! If you underestimate, you can always supplement later."
"Seek used items wherever possible."
"Don't let your inner sentimentalist talk you into saving everything as keepsakes."
That last one is the hardest for me!
