I’m not going to get all lactivist here, but obviously breastfeeding is as green and frugal as you can get, especially with a singleton that you are able to stay home with — no bottles, no pumps, no formula, no waste, no expense, etc. (I had that with my firstborn but have found breastfeeding triplets, though not exclusively, to be incredibly resource intensive in terms of supply-enhancing herbs, pumps and bottles, and the like. Still, I’m happy for what I am able to provide for them!)

Eco Child’s Play has some lovely (and not too preachy) posts up about breastfeeding, and the BabyCenter Store has breastfeeding pumps, pillows, bras and more on sale up to 30% off through 8/24. Plus, you can get free shipping on orders of $49 or more with code FREESHIP49.
