You can change a diaper without completely undressing the bottom half of baby. This is great for the Midwest where there are actually chilly times. Here in Texas, they are great knee protection for crawlers and you don't have to wrestle pants back on after diaper changes! And, since they are made from adult knee socks (or child knee socks for the newborns), your options are almost endless!
There are tutorials everywhere on the inter-web, so I won't bore you with the how-to. I will, however, save you the time - mine are $9/ pair (shipping included) or 3 for $21! Email me at
