What is the one item you just had to have or that everyone told you you had to have?

The worst was a set of disposable diapers; just not good to use. The best purchase I made was a Co – Sleeper and Deluxe All in One Diaper, both from aBaby.com. After many ill fit diapers, I was recommended this by my friend. It has the best fit and absorbency feature. Love it.
