Ours are 8 weeks too, we got them on Friday. Like the others have said its best to have her on water, because milk is more of a meal, yes it has nutrients and things, but water hydrates. Ours love water, took too it straight away, although Poppy likes to put her paw on the bowl whilst drinking so you can imagine how much water has been all over! lol. wouldn't have her any other way though.

Good luck.
