Thanks for all of your replies. That is good to know that you can exchange them if you don't use them. Really good to know about getting boys ones anyway, may do that in the next size up. I posted another thread today as Coles has the smaller packets (half the size of the boxes) for even cheaper. We got some more newborns because they were so cheap and thought if we didn't use them we'd sell them on ebay but it's even better now I know we may be able to exchange them. Will have to check out the boy ones in the next size. Thanks.
