I am not sure of the specific ones, but I recommend using a site like www.myresistry.com
. It is so easy to use and allows you to create a registry from as many different sites as you want, even if they don't specificaly have a registry. I was able to register for cloth diapers from one site, baby first aid kit from another, nursing pillow from another, etc. This also allowed me to shop around and find the best prices. For me it made registering fun, because I was dreading having to pick one like Babies R Us.. yuk!
