We have two babies under 2yo, so we go through a LOT of diapers. Thank GOD for Costco; we buy the Huggies which work out to about 19 cents per diaper and that's about as good as it gets unless you have coupons...for us, that alone has been worth the cost of membership. We did NOT like the Kirkland (Costco's store brand) diapers...too many broken tabs. We love the Kirkland wipes though, and they're considerably less expensive than name brands.
We've used Target and Parent's Choice (Wal-Mart) brand formulas, and both boys have done fine on these. Q has some acid reflux, but we've not had to resort to the pre-digested stuff, and he's in the 85th percentile for weight, so he's doing fine on the store brand formula. We do feed mostly organic foods now that both are eating "people food"; I steam organic apples, sweet potatoes, etc. and puree them. I was excited to find Gerber organics, although sometimes Earth's Best is a better buy, depending on the store. Big surprise: Earth's Best cereal was much cheaper at ToysRUs than at the local grocery store. Bottom line is you just have to look around in your own area and find the best places to shop.
