Luckily we didn't buy any of our useless stuff. We have an assortment of baby seats borrowed from my cousin - swing, bouncy thing, and vibrating chair - but he hates anything that puts him in the slouchy posture.
We also have an assortment of blankets, clothes, and burp cloths that we don't like enough to use. I need to pull out anything that can go to consignment and send the rest to good will -- at least that will help with the taxes
