The bottle sterilizer was a complete waste...as well as the Baby Bjorn and Peanut Shell sling, which have both been used once.
Also, agree with pp about the boppy pillow...it was way easier just to use pillows...so I never really used that as well as its extra cover.
I have about a million burp cloths, blankets, bibs and washcloths that will never be used ( I received them as gifts)...and although people kept telling me I could never have too many...there is no way I could every use them all!
Bumbo...got it as a gift and DS hated it. The Boppy pillow works well for some, I found it cumbersome and bulky. Didn't like the Swaddle Me, Miracle Blankets are fantastic. We didnt know what we were having so we avoided all the ridiculous baby outfits. I can't even imagine putting shoes on a newborn!
There are a lot of things mentioned that we used and still use all the time. I still use receiving blankets, burp cloths and wash cloths everyday. Bassinet, PNP, walker, swing, jumper, Chicco Travel System were/are all musts for us. It really depends on you and your baby. I would buy as you need it and if your friends have things you can try first, that is great too.
